% \section{Introduction}
% Enterprise Modelling and Information Systems Architectures
% --~International Journal of Conceptual Modeling (\DTXclassname, formerly
% abbreviated as EMISA) is a publisher-independent, peer-reviewed open access 
% journal (\url{https://emisa-journal.org}). 
% \DTXclassname is published by the German Informatics Society (GI) and is a 
% publication of its Special Interest Group (SIG) on Modelling Business 
% Information Systems (SIG MoBIS) and its SIG on Design Methods for 
% Information Systems (SIG EMISA). SIG~MoBIS has sponsored the development of 
% the \DTXclassname \LaTeX{} package currently maintained by Stefan Strecker 
% (\href{mailto:stefan.strecker@fernuni-hagen.de}{stefan.strecker@fernuni-hagen.de}) and Martin Sievers 
% (\href{mailto:martin.sievers@schoenerpublizieren.de}{martin.sievers@schoenerpub
% lizieren.de}). It is based on earlier funded work by Martin Leidig.
%
% The \DTXclassname \LaTeX{} package is provided for preparing
% manuscripts for submission to \DTXclassname, and for preparing
% accepted submissions for publication as well as for typesetting the
% final document by the editorial office. For \DTXclassname{},
% manuscripts are submitted online  and accepted articles are
% published online at \url{https://emisa-journal.org} in the Portable
% Document Format (PDF) format. 
% The \DTXclassname editorial office is run (alongside many other tasks and projects) by the two Editors-in-Chief assisted by doctoral students. Editorial work at \DTXclassname is best described as a volunteer effort for the scientific community.
% You can assist us by preparing your manuscript following the instructions and style guidelines described in this document: Your work will be published quicker with less (typographical) glitches and will have a professional appearance.
%
%
% \section{Installation}
% The \DTXclassname \LaTeX{} package consists of the document class 
% \file{\DTXname.cls}, the \pkg{biblatex} bibliography style 
% \file{\DTXname.bbx} and the \pkg{biblatex} citation style 
% \file{\DTXname.cbx}.
% 
% The package also includes a quick-start template for authors 
% (\file{emisa-author-template.tex}) and the present author instructions and 
% style guidelines (\file{\DTXname.pdf}).
%
% \DescribeOption{Automatic installation}The preferred installation
% method of the canonical \emph{release} version is through your
% \TeX{} distribution's package installer (\eg \TeX{}~Live's
% \file{tlmgr} or the MiK\TeX{} Package Manager). For the latter you
% may need to first update (or synchronise) the package database. This
% type of installation is recommended in order to always get the
% latest \emph{release} version automatically. The canonical release
% version of the package is also available from CTAN at
% \url{http://www.ctan.org/pkg/emisa} while the \emph{current
% development} (i.\,e.\ most recent) version of the package with bug
% fixes and new features (relative to the release version) is
% available from the GitHub repository at \url{https://github.com/gi-ev/emisa-latex-package}.
%
% \DescribeOption{Manual installation}If you prefer a manual installation (or 
% want to install the latest development version), download the corresponding 
% Zip archive from Github (the latest development version is always available 
% as Zip archive at 
% \url{https://github.com/gi-ev/emisa-latex-package/archive/master.zip}), 
% uncompress it in the same directory (folder) in which the source files for 
% the manuscript will be maintained, and then run \verb|pdflatex emisa.dtx| 
% twice, and start from \file{emisa-author-template.tex}.
%
%
% \section{Instructions and guidelines}
% This document provides instructions and style guidelines for authors. 
% Follow the instructions and guidelines in the present document to
% set up your files, to type in your text, to format figures, tables,
% source code listings and algorithms, and to obtain a consistent
% visual appearance in accordance with the journal's style
% specifications. Before submitting your manuscript online to the
% journal's online submission system at
% \url{https://emisa-journal.org}, use these instructions and
% guidelines as a checklist. Note that these instructions are \emph{not} 
% intended as a general introduction to \LaTeX2e{} and corresponding tools 
% (see, for example, \url{http://mirror.ctan.org/info/lshort/english/} for 
% \enquote{The Not So Short Introduction to \LaTeX2e{}---Or \LaTeX2e{} in 157 
% minutes}). 
%
%
% \section{Preliminary remarks}
% The \DTXclassname document class is derived from the standard \LaTeX{} 
% article class, and produces a customised two-column layout with 
% bibliographic information about the manuscript in a multi-line page headline 
% (including the name of the journal, volume and issue number, date of 
% publication, short title as well as author names) on A4-sized paper. The 
% \DTXclassname class builds on a number of standard \LaTeX{} packages. It is 
% highly recommended to install the \emph{full} set of \LaTeX{} packages that 
% come with your \LaTeX\ distribution to make the required packages available 
% to the \DTXclassname package. Alternatively, missing packages may be 
% installed via your TeX{} distribution's package manager or on-the-fly (if 
% supported by your distribution). 
%
% \DescribeOption{UTF-8}\DescribeOption{File naming convention}The production 
% process at the \DTXclassname editorial office is based entirely on \LaTeX{}, 
% and runs pdf\LaTeX{} and \verb|biber| to produce the final proof and 
% publication-ready PDF of an article. The \pkg{biblatex} package is used to 
% typeset citations and references in conjunction with the \verb|biber| tool. 
% Make sure to use \verb|biber| rather than \verb|bibtex| to process your 
% bibliography data base file(s). Most \TeX{} editors have an option to easily 
% switch to \verb|biber|. The production tool chain at the editorial office 
% requires that all text files of an article are provided in \emph{UTF-8 file 
% encoding}, and that all submitted files are provided with \emph{lower case 
% filenames only}. Do \emph{not} use upper case characters in filenames at all 
% and avoid non-ASCII characters in filenames.
%
% \DescribeOption{Author template}The file \file{emisa-author-template.tex} 
% provides a good starting point for manuscript preparation (if the 
% \DTXclassname package is available through your \TeX{} distribution, the 
% file is stored at \texttt{/doc/latex/emisa/} inside your \TeX{} installation 
% folder/directory. Just copy it to your working directory). It is also 
% recommended to review the example of an article typeset with 
% \file{\DTXname.cls} provided in Sec.~\ref{sec:example}. 
%
%
% \section{Class Options}
% \DescribeOption{american, USenglish} American English is the language of 
% choice for publishing in \DTXclassname. The class option \opt{american} is 
% loaded by default to obtain the correct hyphenation for American English (as 
% provided by the \pkg{babel} package). The option \emph{may be} explicitly 
% used with the \DTXclassname class to exemplify the use of American English: 
% \verb|\documentclass[american]{emisa}|. Note that the \pkg{csquotes} package 
% is loaded with settings to 
% produce proper quotation marks for American English (see below).\\
% \textbf{Note that versions of this class prior to 2.2.0 used British English 
% as standard language!}
%
% \DescribeOption{british, UKenglish} If you want to use British English 
% instead, you can use the option \opt{british} or \opt{UKenglish}. The 
% hyphenation patterns and quotation marks will be set accordingly.
%
% \DescribeOption{referee, review} By default, a final version of the
% manuscript is typeset for online publication including the names and
% affiliations of authors. For reviewing purposes, the names and
% affiliations of the authors must be omitted using the document option 
% \verb|referee| or \verb|review| to allow for the anonymous (\ie double 
% blind) peer-review process of \DTXclassname. Example: 
% \verb|\documentclass[referee]{emisa}|.  Make sure to set the document option 
% \verb|referee| or \verb|review| before typesetting the final PDF intended 
% for submission to the journal. 
%
%
% \section{Author information}
% \DescribeMacro{\author}\DescribeMacro{\address}%
% Each author is added using the macro \cs{author}\marg{author name} followed 
% by the corresponding address \cs{address}\marg{author's address (line 
% 1)\textbackslash\textbackslash\ \ldots (line 2)\textbackslash\textbackslash\ 
% \ldots}. If you have multiple authors with the same address, please use 
% \cs{address}\marg{author's address} only for the first one and 
% \cs{address}\oarg{letter of address}\texttt{\{\}} for all others. See 
% \file{emisa-author-template.tex} for details.
%
% \DescribeMacro{\author*}There always has to be declared exactly one author 
% as the corresponding author. This is indicated by using the starred version 
% of the \cs{author} command: \cs{author*}\marg{author's name}\marg{email 
% address}.
%
%
% \section{Title, subtitle, abstract, and keywords}
% \DescribeMacro{\title}\DescribeMacro{\subtitle}%
% The mandatory title and optional subtitle of a manuscript are typeset using \cs{title}\marg{title} and \cs{subtitle}\marg{subtitle}. Note that the subtitle is indented.
% \DescribeMacro{\abstract}The abstract of the manuscript is typeset using \cs{abstract}\marg{abstract}. Each manuscript should provide an abstract of about 200--400 words.
% \DescribeMacro{\keywords}%
% Keywords describing the manuscript are typeset using \cs{keywords}\marg{keywords} and are concatenated using the \cs{and} command. At least three keywords should be provided.
%
%
% \section{Additional information on the first (title) page}
% \DescribeMacro{\acknowledgements}%
% Acknowledgements, for example, of collaborators, funding agencies etc.\ may be added using \cs{acknowledgements}\marg{acknowledgements}. The acknowledgements are typeset in a footnote on the first page below the corresponding author's email address.
%
% \DescribeMacro{\authornote}%
% Additional information for reviewers and readers may be added in a footnote on the titlepage using \cs{authornote}\marg{author note}. This is typically used for stating earlier publications (\eg in conference proceedings) on which the present manuscript is based.
%
%
%
% \section{Style guidelines for regular text}
%
% \begin{itemize}
% \item Manuscripts should \emph{not} make use of outdated \LaTeX{} commands such as \verb|\em|, but rather use the \LaTeX2e\ commands (\eg \verb|\emph|, \verb|\texttt|). 
% \item Do \emph{not} make use of bold face (\cs{textbf}). Use \cs{emph} instead to typeset an important word in italics!
% \item Always use the tilde \verb|~| to connect before \cs{ref}\marg{label}, \eg,\ \verb|Sec.~\ref{label}| rather than the problematic: \verb|Sec. \ref{label}|.
% \item Always use the en-dash (\texttt{-{}-}) for ranges -- without spaces -- \eg, \texttt{17-{}-34}. The hyphen (\texttt{-}) should only be used for compound words or hyphenation. 
% \item Do \emph{not} write abbreviations such as \verb|e.g.| but use the macros provided by the \DTXclassname class (see below). Add punctuation when necessary, for example, write \verb|, \ie,| to achieve the correct punctuation for \enquote{id est} (i.\,e.) rather than \verb|, i.e.,| which introduces two problems: A missing spacing after the first full stop and a wrong spacing after the second full stop.
%
%
% \item Follow the journal's style specification with respect to predefined text styles:
% 	\begin{itemize}
% 	\item Use \textsc{smallcaps} for names of open-source projects, products and companies etc., \eg,\ \verb|\textsc{eclipse}| to produce \textsc{eclipse}. \emph{Pay attention to lower case spelling}.
% 	\item \DescribeMacro{\meta}Use \texttt{non-proportional font} for language concepts, meta types, meta classes etc., \ie,\ \verb|\texttt{AbstractGoalType}| to produce \texttt{AbstractGoalType}, or use the predefined macro \cs{meta}\marg{metatype}, \eg,\ \verb|\meta{AbstractGoalType}|.
% 	\item \DescribeMacro{\type}Use the \textsf{sans-serif font face} for type-level concepts etc., \eg,\ \verb|\textsf{Goal}| to produce \textsf{Goal} when referring to a \textsf{Goal} type, or use the predefined macro \cs{type}\marg{type}, \eg,\ \verb|\type{Goal}|.
% 	\end{itemize}
% \end{itemize}
%
%
% \section{Abbreviations and initialisms}
% \DescribeMacro{\eg,\ie,\cf,\etal}%
% To achieve consistent typesetting of common abbreviations, macros are predefined by the \DTXclassname class. These macros should \emph{consistently} being used instead of writing the plain version. For example use \verb|\eg| rather than {\verb|e.g.,|}. The macros take care of spacing within and after the abbreviations. 
% \begin{itemize}
% \item \cs{eg} for e.\,g.
% \item \cs{ie} for i.\,e.
% \item \cs{cf} for cf.
% \item \cs{etal} for et~al.
% \end{itemize}
%
% \DescribeMacro{\emisaabbrv} If you miss any frequently used abbreviation for your article, you can easily add it using \cs{emisaabbrv\marg{\cs{abbreviation\_macro}}\marg{text}} in the preamble of your article.
%
% \DescribeMacro{\OMG,\BPM,\BPMN,\UML}%
% In addition to common abbreviations, further initialisms are provided by the class for convenience and for a consistent visual appearance. Note that the class uses \textsc{smallcaps} for typesetting initialisms. The list of predefined initialisms comprises:
%
% \begin{itemize}
% \item \cs{OMG} for \textsc{omg} (Object Management Group).
% \item \cs{BPM} for \textsc{bpm} (Business Process Management).
% \item \cs{BPMN} for \textsc{bpmn} (Business Process Model and Notation).
% \item \cs{UML} for \textsc{uml} (Unified Modelling Language).
% \end{itemize}
%
% \DescribeMacro{\emisainitialism} You can add your own initialisms by stating \cs{emisainitialism\marg{\textbackslash initialism\_macro}\marg{text}} in the preamble.
% 
%
% \section{Quotation marks}
% \DescribeMacro{\enquote}%
% It is \emph{highly recommended} to use the \cs{enquote}\marg{quotation} command to produce correct quotation marks. Note that the command can be nested and will produce correct primary and secondary quotation marks in American English (or British English -- depending on the chosen class option), for example \verb|\enquote{A quote \enquote{within a quote}}|.
% For other quotation macros and environment please consult the \pkg{csquotes} documentation \cite{csquotes-pdf}.
%
% Alternatively (but not recommended), the correct Unicode characters for the quotation marks in American (British) English can be used. See Wikipedia's entry for \enquote{quotation mark} for further information.  
%
% \section{Citations and references}
% \DescribeMacro{\parencite}\DescribeMacro{\textcite}\DescribeMacro{\cite}%
% The \DTXclassname journal uses its own author-year citation style predefined for the \pkg{biblatex} package (\file{emisa.cbx}), and its own style for formatting entries in the list of references (\file{emisa.bbx}). Consult the \pkg{biblatex} package documentation \cite{biblatex-pdf} for an introduction to the citation commands.
%  It is important to use the citation commands properly to follow the journal's style specifications.
%
% \begin{itemize}
% \item \cs{parencite} is used for citing in parentheses (usually at the end of a sentence). In most cases, page numbers should be provided. Example: \verb|\ldots{} is known \parencite[5]{Knuth1986}| produces \enquote{\ldots{} is known (Knuth 1986, p.~5)}. Also use \cs{parencite} to produce a prefix within parentheses, e.\,g.\ \verb|\ldots{} is known \parencite[for a justification, see][5]{Knuth1986}| produces \enquote{\ldots{} is known (for a justification, see Knuth 1986, p.~5)}. 
%
% \item \cs{textcite} allows for using the cited work as a subject in the grammatical structure of a sentence. Example: \verb|\textcite{Knuth1986} states that ...| produces \enquote{Knuth (1986) states that \ldots}. Additionally, page numbers and further information can be provided, see the \pkg{biblatex} package documentation.
%
% \item \cs{cite} is used for typesetting the citation without parentheses, and is typically used within parentheses. Example: \verb|(see \cite{Knuth1986})| produces \enquote{(see Knuth 1986)}. This variant is the least used and should be used with care.
% \end{itemize}
%
% \textbf{Important note.} \emph{Make sure to format the bibliographic entries consistently!} Do not mix abbreviated first names with unabbreviated first names, as for example
%		
% \verb|@ARTICLE{key1, author = {{van der Weiden}, J. W. P.} ...|  
% 
% \verb|@ARTICLE{key2, author = {{van der Weiden}, Jan W. P.} ...|
% 
% if both entries refer to the same author. This will lead to unexpected results with respect to the label generation of the citation. Make sure to always abbreviate author first names and to always use use curly brackets around multi-word last names, \eg \verb|{van der Weiden}, J. W. P.| in the bibentries.
%
% \section{Figures}
% All line-drawings must be provided as vector graphics (\emph{not} bitmap graphics) in PDF format and all other (non-schematic) figures (\eg screenshots) must be provided in PDF, JPEG or PNG format in a proper (high) resolution for the intended size of the rendered image to avoid pixelation due to low resolution; bitmap graphics shown in full page width in the submission should at least be of a resolution of two (2) megapixels or at least 1920 pixels wide.
%
%
% \section{Tables}
% \DescribeEnv{tabular}Tables can be added using the standard notation, \ie using \env{tabular} inside the floating environment \env{table} (see Listing~\ref{lst:tabular}). However, the standard column parameters \opt{p}, \opt{l}, \opt{c} and \opt{r} are often not sufficient to provide a table with an exact width, \eg the text width.
% \begin{lstlisting}[caption={An example for a standard table using \env{tabular}},label={lst:tabular}]
% \begin{table}
% \small % or \footnotesize if needed at all
% \centering % if needed
% \caption{Add the caption here}
% %\label{tab:unique-label} % alternatively after \end{tabular}
% \begin{tabular}{p{3cm}lcr}
% \toprule
% A column 3cm wide and with possible line breaks &
% \midrule
% A column set flush-left with no line breaks &
% A column set centred  with no line breaks &
% A column set flush right with no line breaks \\
% \bottomrule
% \end{tabular}
% \label{tab:unique-label}
% \end{table}
% \end{lstlisting}
%
% \DescribeEnv{tabularx} Therefore the \DTXclassname class loads the package \pkg{tabularx} by default. It defines an additional column parameter \opt{X}, which has to be used for at least one column. In addition the standard \env{tabular} environment is substituted by \env{tabularx} which has two mandatory arguments, namely the total width of the table and the definition for the columns.
%
% Listing~\ref{lst:tabularx} shows two typical examples for the application of \env{tabularx}. If you just mark one column with the parameter~\opt{X}, all other columns (\ie columns with parameters \opt{p}, \opt{l}, \opt{c} or \opt{r}) are set the usual way. The remaining width (width given as first argument to \env{tabularx} minus used width of all \enquote{non-X-columns}) is then assigned to the \opt{X}~column. To get a table two columns wide, please use \cs{textwidth} as the table's width.
% \begin{lstlisting}[caption={An example for a table using the package \pkg{tabularx} for exactly one \opt{X} column},label={lst:tabularx}]
% ...
% \begin{tabularx}{\textwidth}{Xll}
% This a column with possibly long text passages, 
% so that line breaking is necessary and automatically 
% applied by the X column & This column is set ragged right and gets as wide as its contents &
% Another column \\
% ...
% \end{tabularx}
% ...
% \end{lstlisting}
%
% A second frequently used scenario is the need for columns with equal width, but without having to calculate the value manually. For a much more comfortable solution one can assign the \opt{X} parameter to all such columns.
% \begin{lstlisting}[escapechar=§,caption={An example for a table using the package \pkg{tabularx} and more than one \opt{X} column},label={lst:tabularx-var}]
% ...
% \begin{tabularx}{\textwidth}{p{3cm}XXX}
% This a column with possibly long text passages, 
% so that line breaking is necessary and automatically 
% applied to get a box 3cm wide &
% This column and the remaining two all have the same width, namely
% (\textwidth-3cm)/3. & 
% ...
% \end{tabularx}
% ...
% \end{lstlisting}
%
% Additional information can be obtained from the package's documentation \cite{tabularx-pdf}.
%
% For nicer tables you should get rid of any vertical lines between the columns. Instead you can use the macros provided by \pkg{booktabs} (preloaded by \DTXclassname) for horizontal lines of different width. Just replace the first standard \cs{hline} by \cs{toprule}, the last one by \cs{bottomrule} and all other by \cs{midrule}. There is even an alternative for \cs{cline} called \cs{cmidrule}. The example from Listing~\ref{lst:tabularx-var} then looks like:\clearpage
% \begin{lstlisting}[escapechar=§,caption={An example for a table using the packages \pkg{tabularx} and \pkg{booktabs}},label={lst:tabularx-booktabs}]
% ...
% \begin{tabularx}{\textwidth}{p{3cm}XXX}
% \toprule
% Table header 1 & table header 2 & table header 3\\
% \midrule
% This a column with possibly long text passages, 
% so that line breaking is necessary and automatically 
% applied to get a box 3cm wide &
% This column and the remaining two all have the same width, namely
% (\textwidth-3cm)/3. & 
% ...
% \bottomrule
% \end{tabularx}
% ...
% \end{lstlisting}
%
% Have a look at the package's documentation \cite{booktabs-pdf} for more details.
%
% \section{Source code listings}
% \DescribeEnv{sourcecode}\DescribeEnv{java}For marking up source code listings, the \DTXclassname class uses the \pkg{listings} package (see the package documentation \cite{listings-pdf} for further information), and provides two customised \LaTeX{} environments: \env{sourcecode} and \env{java}. The \env{java} environment should be used to format source code listings in the Java programming language, and the \env{sourcecode} environment should be used to format source code in any other programming language. You can add the name of the programming language and other parameters known to \pkg{listings} like \opt{caption} or \opt{label} as an optional argument.
%
% Note that the source code in either case is typeset verbatim, \ie, the author must arrange the input \LaTeX{} source code according to the intended output. Also note that the two environments have been predefined to always produce a two-column listing positioned at the top of the page. Listing~\ref{lst:sourcecode} illustrates the use of both environments.
% \begin{examplecode}[caption={Example for the \env{java} and \env{sourcecode} environments},label={lst:sourcecode}]
% \begin{java}[caption={A hello world example},label={hw-java}] 
% public class HelloWorld 
% {
%    public static void main (String[] args)
%    {
%       // Output Hello World!
%       System.out.println("Hello World!");
%    }
% }
% \end{java}
%
% \begin{sourcecode}[language=R]
%   hello <- function( name ) {
%      sprintf( "Hello, %s", name );
%   }
% \end{sourcecode} 
% \end{examplecode}
%
% \section{Pseudo-code and algorithms}
% \DescribeEnv{algorithm}\DescribeEnv{algorithmic}Apart from source code you might want to add pseudo code examples or algorithms. In contrast to the source code examples above \DTXclassname does not define its own environments for that. Instead we recommend using the bundle \pkg{algorithms} consisting of the two packages \pkg{algorithm} and \pkg{algorithmic}. Typical parts like loops, if-clauses or statements all have their own macro. See Listing~\ref{lst:pseudocode} for an example.
% \begin{examplecode}[caption={Example for a pseudocode presented within the \env{algorithmic} environment},label={lst:pseudocode}]
% \begin{algorithmic}[1]
% \REQUIRE $n \geq 0$
% \ENSURE $y = x^n$
% \STATE $y \leftarrow 1$
% \STATE $X \leftarrow x$
% \STATE $N \leftarrow n$
% \WHILE{$N \neq 0$}
% \IF{$N$ is even}
% \STATE $X \leftarrow X \times X$
% \STATE $N \leftarrow N / 2$
% \ELSE[$N$ is odd]
% \STATE $y \leftarrow y\times X$
% \STATE $N \leftarrow N - 1$
% \ENDIF
% \ENDWHILE
% \end{algorithmic}
% \end{examplecode}
% results in
% \begin{algorithmic}[1]
% \REQUIRE $n \geq 0$
% \ENSURE $y = x^n$
% \STATE $y \leftarrow 1$
% \STATE $X \leftarrow x$
% \STATE $N \leftarrow n$
% \WHILE{$N \neq 0$}
% \IF{$N$ is even}
% \STATE $X \leftarrow X \times X$
% \STATE $N \leftarrow N / 2$
% \ELSE[$N$ is odd]
% \STATE $y \leftarrow y\times X$
% \STATE $N \leftarrow N - 1$
% \ENDIF
% \ENDWHILE
% \end{algorithmic}
%        
% If you want your algorithm to be a floating object, you can surround it with \env{algorithm}:
% \begin{examplecode}
% \begin{algorithm}
% \caption{Calculate $y = x^n$}
% \label{alg1}
% \begin{algorithmic}
% ...
% \end{algorithmic}
% \end{algorithm}          
% \end{examplecode}
%   
% For more details, please have a look at the documentation \cite{algorithms-pdf}.

% 
% 
% This loads font definitions for text and mathematics. 
% The package allows the user to select font encodings, and for each
% encoding provides an interface to `font-encoding-specific' commands
% for each font.  Its most powerful effect is to enable hyphenation to
% operate on texts containing any character in the font.
% It is distributed as part of the \LaTeXe{}
% distribution.
%    \begin{macrocode}
\RequirePackage[T1]{fontenc}%
%    \end{macrocode}
% 
% Since many PostScript fonts only implement a subset of the \opt{TS1}
% encoding which contains text symbols for use with the

% letterspacing (tracking) and the possibility to disable all or

% 
% This style option improves the interface for defining floating
% objects such as figures and tables in \LaTeX{}~\cite{float-pdf}. It adds the notion of
% a `float style' that governs appearance of floats.  New kinds of
% floats may be defined using a \cs{newfloat} command analogous to
% \cs{newtheorem}.  This style option also incorporates the
% functionality of David Carlisle's style option \pkg{here}, giving
% floating environments a \texttt{[H]} option which means \emph{Put
% it here!} (as opposed to the standard \texttt{[h]} option which
% means \emph{Put it here if possible, or otherwise at the next page if 
% no alternative position is specified.}).
%    \begin{macrocode}
\RequirePackage{float}
%    \end{macrocode}
%

% \env{table}. Furthermore it does similar to the caption stuff coming from
% other packages (like the \pkg{longtable} or \pkg{supertabular} package)~\cite{caption-pdf}.

% access to several kinds of colors, tints, shades, tones, and mixes
% of arbitrary colors by means of color expressions~\cite{xcolor-pdf}.
% \iffalse
% It allows to select a document-wide target color model and offers tools for
% \begin{itemize}
%   \item automatic color schemes,
%   \item conversion between twelve (sic!) color models (rgb, cmy, cmyk, hsb,
%     Hsb, tHsb, gray, RGB, HTML, HSB, Gray, wave)
%   \item alternating table row colors,

% The \pkg{biblatex} package~\cite{biblatex-pdf} is a complete reimplementation of the
% bibliographic facilities provided by \LaTeX{} in conjunction with
% \BibTeX. It redesigns the way in which \LaTeX{} interacts with BibTeX at
% a fairly fundamental level. With \pkg{biblatex}, \BibTeX{} is only used to
% sort the bibliography and to generate labels. Instead of being
% implemented in \BibTeX{}'s style files, the formatting of the
% bibliography is entirely controlled by \TeX{} macros. Good working
% knowledge in \LaTeX{} should be sufficient to design new bibliography
% and citation styles. There is no need to learn \BibTeX{}'s postfix stack
% language. Just like the bibliography styles, all citation commands
% may be freely (re)defined.
% 
% Apart from the features unique to \pkg{biblatex}, the package also
% incorporates core features of the following packages: \pkg{babelbib},
% \pkg{backref}, \pkg{bibtopic}, \pkg{bibunits}, \pkg{chapterbib}, \pkg{cite},
% \pkg{citeref}, \pkg{inlinebib}, \pkg{mlbib}, \pkg{multibib}, \pkg{natbib},
% \pkg{splitbib}. There are also some conceptual parallels to the \pkg{amsrefs}
% package. The \pkg{biblatex} package supports split bibliographies, multiple
% bibliographies within one document, and separate lists of bibliographic
% shorthands. Bibliographies may be subdivided into parts (by chapter, by
% section, etc.) and/or segmented by topics (by type, by keyword, etc.). The
% package is fully localized and can interface with the \pkg{babel} package.
% 
% This package requires e-\TeX{} and the \pkg{etoolbox} package. Installing
% the \pkg{csquotes} package is recommended.
%    \begin{macrocode}
\RequirePackage{etoolbox}%
%    \end{macrocode}
% 
% We use it with these options:
% \begin{compactdesc}
%   \item{\opt{style=emisa}} sets the base name of the bibliography and 
%   citation format files; thus we use \file{emisa.bbx} and 
%   \file{emisa.cbx} that are defined below.
%   \item{\opt{natbib=true}} enables the use of \pkg{natbib} citation 
%   commands with \pkg{biblatex}.
%   \item{\opt{maxcitenames=3}} Author lists with more than two entries are 
%   abbreviated with \enquote{et al.}.  Note that in the bibliography 
%   listing  author lists won't be shortened at all.\footnote{That is, 
%   they \emph{will} be shortened if there are more than 999 
%   authors.  That should occur not that often, though.}
%   \item{\opt{terseinits}} If Initials are given with (false) or
%   without (true) punctuation and whitespace.
%   \item{\opt{isbn=false}} In bibliographies, no ISBNS, \ldots
%   \item{\opt{url=false}} \ldots\ no URLs, \ldots
%   \item{\opt{doi=false}} \ldots\ no DOIs, \ldots
%   \item{\opt{eprint=false}} \ldots\ and no ePrint marks are   displayed.
%   \item{\opt{dashed=false}} Identical author entries of consecutive
%   bibliography entries don't get replaced by a dash (beginning with the second one).

% environments~\cite{environ-pdf}.
%    \begin{macrocode}
\RequirePackage{environ}%

% 
% \pkg{paralist} provides a few new list environments. Itemized and enumerated

% version. Most environments have optional arguments to format the labels.
% Additionally, the \LaTeX{} environments itemize and enumerate can be 
% extended to use a similar optional argument~\cite{paralist-pdf}.
% 
% The options' meanings are as follows:
% \begin{description}
% \item{\opt{neveradjust}\quad} The width of the labels is never
% adjusted, not even for environments where you defined the labels
% manually using the optional argument.
% \item{\opt{defblank}\quad} The two environments \env{inparablank} 
% and \env{asparablank} will be defined.

% \pkg{afterpage} implements a command that causes the commands

% 
% The \pkg{xspace} package provides a single command that looks

% insert a space to replace one ``eaten'' by the \TeX{} command decoder.
% The decision is based on what came after any space, not on whether
% there was a space (which is unknowable): so if the next thing proves
% to be punctuation, the chances are there was no space, but if it's a
% letter, there's probably a need for space~\cite{xspace-pdf}.
%

% entry, if there is any:

% If \emph{no} optional argument is given the obligatory argument 
% will appear in all the respective places.
% 
% If \emph{one} optional argument is given then its' value replaces 
% both the \emph{short} and the \emph{ToC} entries.
% 
% If \emph{two} optional arguments are given then the value of the
% first one becomes the \emph{short} headline (et al.)  entry, and 
% the second one is reproduced in the table of contents.
% 
% If \emph{both} optional arguments are given but the
% first one is left empty then the \emph{short} entry defaults also 
% to the main value, and only the \emph{ToC} entry is changed.

% \subsubsection{Page styles}

% This is the standard page style:
% \begin{description}
%   \item{\textbf{Page Head:}} three lines of text, \cs{textwidth}
%   wide and aligned to the inner and outer text body borders,
%   respectively, each above a black horizontal line at full sheet
%   width.  The text entries comprise:
%   \begin{enumerate}[{Line\,}1{,\space\hskip-1em}]
%   \item
%     \begin{description}
%       \item{inner side:}
%     \begin{itemize}
%       	\item{left pages:} journal's subtitle;
%        \item{right pages:} journal name.
%     \end{itemize}
%       \item{outer side:} no text.
%     \end{description}
%   \item 
%     \begin{description}
%       \item{inner side:} volume/number/issue date, 
%         text colour is 50\,\% grey;
%       \item{outer side:} no text.
%     \end{description}
%   \item  
%     \begin{description}
%       \item{inner side:} 
%         \begin{itemize}
%           \item{left pages:} section name;
%           \item{common right pages:} author's name(s);
%           \item{editorial content, both sides:} section or category 
%           name;
%         \end{itemize}
%       text colour is 50\,\% grey;
%       \item{outer side:} page number in bold type, coloured black,
%       shifted by an amount of \cs{headpageoffset} to the outer edge
%       of the page.
%     \end{description}
%  \end{enumerate}
%  
%  \item{\textbf{Page foot:}} Mostly empty; sometimes in editorial
%   content sections it shows a black horizontal line from the outer text
%   edge to the inner sheet edge (spine).
% \end{description}
% 
% \begin{macro}{\headwidth}
% \begin{macro}{\headmargin}
% Basic lengths for head and foot elements. \cs{headwidth} is the 
% overall width of the headbox equalling the page width plus a bleed 
% of three millimeters.  It is logically restricted to \cs{textwidth} 
% by substracting \cs{headmargin} at both sides.
% \begin{macro}{\bleed}
% \emph{Bleed} is a printing term that refers to printing beyond the edge of
% the sheet after trimming.  The \cs{bleed} is a measure describing
% the (small) amount of space by which objects on the border of your
% document will extend.  Please note that this length is not added 
% automatically, but has to be added manually.
% \begin{macro}{\footrulewidth}
% The width of the foot rule.  As it is drawn asymmetrically (running 
% from the outer text edge to the spine) it has to be a bit smaller 
% than the head box.
% \begin{macro}{\headfootruleheight}
% This is the width of all lines in head and foot.
%    \begin{macrocode}

      The GI-SIG-MoBIS portal provides numerous resources on enterprise
      modelling research, such as a full-text digital library, a
      bibliography, conference announcements, a glossary and evaluation
      reports.  It is intended to establish the premier forum for an
      international community in enterprise modelling.  The new version
      is based on a Content Management System allowing authorized users
      to conveniently upload content.  A \BibTeX{} interface allows for
      conveniently integrating bibliographic data.  Information about
      this journal, such as guidelines for authors, tables of content
      and full-text access to articles (for GI-SIG-MobIS members only)
      are also available on the~portal.

  The journal \emph{\@journalname} is the official journal of the
  Special Interest Group on Modelling Business Information Systems
  within the German Informatics Society (GI-SIG MoBIS).

  The journal Enterprise Modelling and Information Systems
  Architectures is intended to provide a forum for those who prefer a
  design-oriented approach.  As the official journal of the German
  Informatics Society (GI-SIG-MoBIS), it is dedicated to promote the
  study and application of languages and methods for enterprise
  modelling -- bridging the gap between theoretical foundations and
  real world requirements.  The journal is not only aimed at
  researchers and students in Information Systems and Computer
  Science, but also at information systems professionals in industry,
  commerce and public administration who are interested in innovative
  and inspiring concepts.

  The journal's editorial board consists of scholars and practitioners
  who are renowned experts on various aspects of developing, analysing
  and deploying enterprise models.  Besides Information Systems, they
  cover various fields of Computer Science.

  \section*{Subscription Information}

  The journal is distributed free of charge for members of the
  GI-SIG-MoBIS. Membership can be acquired through the German
  Informatics Society (http://www.gi-ev.de/verein/mitgliedschaft/).

  The journal serves to publish results of innovative research on all
  facets of creating and analysing enterprise models and information
  systems architectures.  For research papers, it is required to
  satisfy academic standards in terms of originality, level of
  abstraction and justification of results.  Experience reports serve
  to describe and analyse success stories as well as practical
  obstacles and resulting research challenges.  Topics covered by the
  journal include, but are not restricted to the following subjects:
  \begin{itemize}
    \item  Languages and Methods for Enterprise Modelling 
    \item  Reusable Domain Models (Reference Models) 
    \item  Analysis and Design Patterns 
    \item  Modelling of Business Processes and Workflows 
    \item  Process-Oriented System Architectures 
    \item  Component-Oriented System Architectures 
    \item  Conceptual Modelling for Component-Oriented Design 
    \item  Ontologies for Enterprise Modelling 
    \item  Modelling for Enterprise Application Integration 
    \item  Modelling for Data Warehouses 
    \item  Modelling to support Knowledge Management 
    \item  Model-Driven Development 
    \item  Aspect-Oriented Design 
    \item  Agile Methods for Enterprise Modelling 
  \end{itemize}
  Authors are asked for electronic submissions, which have to be sent
  to the editor in chief as e-mail attachment.  In case of multiple
  authors, it is required to name one author who acts as contact
  person.  The submission should include a cover page with the paper's
  title and the names, affiliations and e-mail addresses of all
  authors.  The first page of the paper starts with the title and does
  not carry the authors' names.  A manuscript must be either in MS
  Word or PDF format.  It should not exceed 5.000 words -- this
  includes an abstract of around 150 words.

  Submitted papers will be reviewed within no more than two months.
  The review process is double blind.  Authors who submit a manuscript
  guarantee that it has not been published elsewhere, nor is intended
  to be published elsewhere.  Papers that were accepted for
  publication must be written according to the style defined for the
  journal.  A comprehensive description as well as a corresponding
  Word template is provided on the web portal of the GI-SIG-MobIS
  (http://www.fg-mobis.gi-ev.de/).}

% \subsubsection{Sectioning}
% \label{sec:code:markup:sec}
% 
% \begin{macro}{\@sect}
% This internal macro facilitates the representation of unstarred
% sectioning commands using \cs{@startsection}.  
% \begin{syntax}
% \cs{@sect}\marg{\#1:\,name}\marg{\#2:\,level}%
%   \newline\hspace*{1em}\marg{\#3:\,indent}\marg{\#4:\,beforeskip}\marg{\#5:\,afterskip}%
%   \newline\hspace*{1em}\marg{\#6:\,style}\oarg{\#7:\,toc-heading}\marg{\#8:\,heading}
%  \end{syntax}
% Here is the meaning of all these parameters:
% \begin{compactdesc}
%   \item[\meta{name}] 
%   \label{list:code:markup:sec:param}%
%   The name of the current sectioning level, e.g., «subsection».
%   
%   \item[\meta{level}] 
%   The level number, describing the hierarchical depth of the current
%   sectioning level named in -- e.g., chapter~=~1, section~=~2, etc. This is 
%   used namely in the tabel of contents.
%   
%   \item[\meta{indent}] 
%   The indentation of the heading, relative to the left margin.  Positive 
%   values shift the heading to the right («inward»), negative
%   values to the left («outward»).
%   
%   \item[\meta{beforeskip}] 
%   The absolute value represents the space to leave above the
%   heading. If the value is negative,  the first paragraph indent following the
%   heading is suppressed.
%   
%   \item[\meta{afterskip}] 
%   If positive, then the section heading is typeset on its own line and the
%   value determines the amount of vertical space to leave below the heading.
%   If negative, then the section heading is typeset run-in and the absolute
%   value determines the amount of horizontal space to leave between the heading
%   and the following text.
%   
%   \item[\meta{style}] 
%   Commands to set the output style. Since he June 1996 release of \LaTeXe{}
%   the \emph{last} command in this argument may be a command such as
%   \cs{MakeUppercase} or \cs{fbox} that takes an argument. The section heading
%   will be supplied as the argument to this command. So setting this to, say,
%   «\cs{bfseries}\cs{MakeUppercase}» would produce bold, uppercase headings.
%   
%   \item[\meta{toc-heading}] 
%   The optional string to be output in the table of contents (toc). If not
%   given, the value from \meta{heading} is used.
%   
%   \item[\meta{heading}] 
%   The heading text to be output in the text body.
% 
% \end{compactdesc}
% These parameters are used also in more high-level sectioning macros upto the familiar
% user level commands defined below.

%    \begin{macrocode}

    \refstepcounter{#1}%
%    \end{macrocode}
% Since \cs{@seccntformat} might end with an improper \cs{hskip} which is
% scanning forward for \arg{plus} or \arg{minus} we end the definition of
% \cs{@svsec} with \cs{relax} as a precaution.

%  All the user level sectioning commands are defined using \cs{@startsection}.
%
%  Normally the corresponding section level counter is incremented and printed
%  out; the exact output is determined by the definition of the corresponding
%  \cs{the\ldots} macro. Additionally, the command uses the counter
%  \arg{secnumdepth} to determine the highest section level to be numbered at
%  all.  
%  If an asterisk (\arg{*}) follows the command, then the corresponding section
%  level counter is \emph{not} used and \emph{no} \oarg{altheading} argument is

% \subsection{Bibliographies}
% \label{sec:code:bib}
% 
% The infrastructure for that is already present in
% \LaTeX{}~\cite[ltbibl.dtx]{source2e-pdf} so we have to tinker with just a couple of
% things.
% 
% \begin{macro}{\bibliography}
% \pkg{biblatex} defines this macro in a way
% that it prescribes the bibliography data base(s) globally for the whole of the
% document. As we need a means to use different bibliography data bases with
% different articles, we redefine \cs{bibliography} such that it
% \begin{inparaenum}
%   \item\label{list:code:bib:bib-requirements:a}%
%   works globally (\pkg{biblatex} style), when used in the 
%   preamble;
%   \item\label{list:code:bib:bib-requirements:b}%
%    works locally in the document body (as defined here);
%   and
%   \item\label{list:code:bib:bib-requirements:c}%
%    appends locally to any globally given bibliography data base(s).
% \end{inparaenum}
% 
% Point~\ref{list:code:bib:bib-requirements:a} is met simply by postponing the 
% redefinition until \cs{begin\{document\}}.  That way we have the unchanged

% \subsubsection{The \protect\DTXclassname bibliography style}
% \label{sec:code:emisa-bbx}
% 
% A \pkg{biblatex} \emph{bibliography style} is a set of macros used to output
% the entries in the bibliography. Bibliography styles are defined in files with
% the suffix \file{bbx}.  The selected one is loaded at the end of the \pkg{biblatex} 
% package.
% 
% Here we produce the \DTXclassname bibliography style by the not so very
% surprising name \file{\DTXname.bbx}. This file will be generated on
% installation from the following code lines between the \texttt{<*bbx>} and
% \texttt{</bbx>} meta-tags.
%    \begin{macrocode}
%<*bbx>
%    \end{macrocode}
% We start by declaring the file name and date.
%    \begin{macrocode}
\ProvidesFile{emisa.bbx}[2016/07/18 2.1.1 EMISA bibliography style]
%    \end{macrocode}
% The \DTXclassname bibliography style is  built on top of the standard style \file{authoryear.bbx}
% being loaded here \ldots
%    \begin{macrocode}
\RequireBibliographyStyle{authoryear}
%    \end{macrocode}
% \ldots\ to be expanded and modified in the following.
% \begin{macro}{\bibitemlabel}

% In the bibliography listings we want the name lists not to be abbreviated.
% Well, a name list containing more than 999 names \emph{will} be abbreviated
% nevertheless; but then, having a name list \emph{this} long might be a problem in
% itsself.

% \paragraph{Formatting commands: punctuation and spacing, blocks and units}
% \label{sec:code:formatting-commands}
% 
% The following code is taken from \file{biblatex.def} and modified at several
% places (see comments). These are some basic and/or generic macros and might be
% superseded afterwards by definitions taken from \file{standard.cbx} or
% \file{authoryear.cbx}.
% 
% The major segments of a bibliography entry are ‚Äòblocks' and ‚Äòunits'. 
% A block is the larger segment of the two, a unit is shorter or at most equal
% in length.
% For example, the values of fields such as title or note usually form a unit
% which is separated from subsequent data by a period or a comma.
% A block may comprise several fields which are treated as separate units, for
% example publisher, location, and year.
% An entry is segmented by inserting \cs{newblock} and
% \cs{newunit} commands at suitable places and \cs{finentry} at the very end.
% The actual printed output of these is defined in the corresponding 
% \cs{\ldots punct} macros.
% 
% The following commands add punctuation marks but automatically prevent
% doubling and remove preceding whitespace. Note that the behavior described
% below is the package default which is adjustable using
% \cs{DeclarePunctuationPairs}. Just the commands used in \DTXclassname are
% discussed here.
% \begin{compactdesc}
% 
%   \item[\cs{addperiod}] 
%   adds a period unless it is preceded by an abbreviation dot or any other
%   punctuation mark. This command may also be used to turn a previously
%   inserted abbreviation dot into a period, for example at the end of a
%   sentence.
%   
%   \item[\cs{addcomma}] 
%   adds a comma unless it is preceded by another comma, a semicolon, a colon, or a period.
%   
%   \item[\cs{addcolon}] 
%   adds a colon unless it is preceded by a comma, a semicolon, another colon,
%   or a period.
% 
%   \item[\cs{isdot}]
%   turns a previously inserted literal period into an abbreviation dot. In
%   contrast to \cs{adddot}, nothing is inserted if this command is not preceded by
%   a period.
% 
% \end{compactdesc}
% The following macros insert space.
% \begin{compactdesc}
% 
%   \item[\cs{addspace}]
%     adds a breakable interword space.
%     
%   \item[\cs{addhighpenspace}]
%     adds a space penalized by the value of the \arg{highnamepenalty} counter which
%     holds a penalty affecting line-breaking in names; please refer to the
%     \pkg{biblatex} manual for explanation. The counter is initialized to
%     \cs{hyphenpenalty} at load-time. Higher values lower the number of
%     linebreaks and vice versa. The traditional \BibTeX behavior (no linebreaks
%     at highnamepenalty breakpoints) is reached by setting it to ‚Äòinfinite'
%     ($\geq 10\,000$).
%  
%   \item[\cs{addlowpenspace}]
%     adds a space penalized by the value of the \arg{lownamepenalty} counter,
%     similar to \arg{highnamepenalty}. The counter is initialized to
%     0.5\,\cs{hyphenpenalty} at load-time.
% 
% \end{compactdesc}
% 
% \begin{macro}{\newunitpunct}
%  The separator inserted between "`units"' in the sense explained above.
%  Here, the definition is just a space.
%    \begin{macrocode}
\renewcommand*{\newunitpunct}{\space}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\finentrypunct}
%  This inserts the punctuation printed at the very end of every bibliography entry. 
%  Here it is simply nothing.
%    \begin{macrocode}
\renewcommand*{\finentrypunct}{\relax}
%    \end{macrocode}
% \end{macro}
% 
% \cs{bibsetup} is a generic hook controlling the (low-level) layout of
% the bibliography and the list of shorthands. The default
% definition should work fine in most cases.
%    \begin{macrocode}
\renewcommand*{\bibsetup}{%
  \interlinepenalty=5000\relax
  \widowpenalty=10000\relax
  \clubpenalty=10000\relax
  \biburlsetup
  \flushbottom
  \frenchspacing
  \sloppy}
%    \end{macrocode}
% The penalties above are not specific to \pkg{biblatex} but
% low-level TeX features. 
% \begin{compactitem}
% 
% \item \cs{interlinepenalty} is the penalty assigned
% to page breaks within a paragraph (i.\,e., in this case, a
% bibliography entry); 
%   
% \item \cs{clubpenalty} is an additional penalty
% assigned to page breaks after the first line of a paragraph;
%   
% \item \cs{widowpenalty} is an additional penalty assigned to page breaks
% before the last line of a paragraph.
%   
% \end{compactitem}
% Note that the value 10000
% means «infinite» as far as TeX is concerned. Setting some penalty to
% 10000 will unconditionally suppress the respective breakpoint.
%
% The net effect of the above settings is as follows. Breaking a
% bibliography entry across pages is discouraged, but not suppressed
% altogether. If a bibliography entry spans less than four lines,
% TeX will always keep it on one page. If it spans four or more
% lines, it may be broken across pages, provided that there are at
% least two lines on the page before and after the break.
%
% These penalties should normally be used in conjunction with
% \cs{raggedbottom}. If you don't like that and remove \cs{raggedbottom}
% from the definition of \cs{bibsetup}, make sure to provide some
% stretchability between bibliography entries by setting \cs{bibitemsep}
% to a suitable value, e.g.:
% \begin{Verbatim}[gobble=4,numbers=none]
%   \setlength{\bibitemsep}{0.5\baselineskip plus 0.5\baselineskip}
% \end{Verbatim}
% 
% \begin{macro}{\biburlsetup}%   
% This is some local setup in order to use \cs{url} properly.
% 
% To ease the job of folding long URLs into narrow columns the following code
% allows linebreaks after numbers as a last resort. The macro also allows breaks
% after hyphens and adjusts \cs{Urlmuskip} to add some stretchability to
% URL~strings.
% 
%    \begin{macrocode}
\renewcommand*{\biburlsetup}{%
  \Urlmuskip=0mu plus 2mu\relax

% \paragraph{Miscellaneous field formatting directives}
% \label{sec:code:bib:formatting-misc}
% 
% This subsection introduces \pkg{biblatex} commands and utility macros used to
% define the formatting directives required by the data commands.
% ^^A see~p.\,\pageref{sec:code:bib:data-commands}.
%     
% The following list shows a few frequently used ones; those more rarely used
% are described below.  
% \begin{compactdesc}
% 
%   \item[\cs{DeclareFieldFormat\oarg{entry type}\marg{format}\marg{code}}]
%     defines the formatting code given in \meta{code} to be executed by
%     \cs{printfield} on processing the field \meta{format}. The value of the
%     field will be passed to \meta{code} as its first and only argument. If an
%     \meta{entry type} is specified, the format is specific to that type;
%     otherwise it applies to all entry types defined. The name of the field
%     currently being processed is available in \cs{currentfield}.
%    
%   \item[\cs{DeclareFieldAlias\oarg{entry type}\marg{alias}\oarg{format entry type}\marg{format}}]
%     declares \meta{alias} to be an alias of the field format \meta{format}. If
%     an \meta{entry type} is specified, the alias is specific to that type. The
%     \meta{format entry type} is the entry type of the backend format. This is
%     only required when declaring an alias of a type specific formatting
%     directive.
% 
%   \item[\cs{bibstring\oarg{wrapper}\marg{key}}] 
%     prints the bibliography string identified by \meta{key}. The string will
%     be capitalized as required. Depending on the \opt{abbreviate} package
%     option, \cs{bibstring} prints the short or the long version of the string.
%     If bibliography strings are nested, i.\,e., if \cs{bibstring} is used in
%     another string, it will behave like \cs{bibxstring}. If the \meta{wrapper}
%     argument is given, the string is passed to the \meta{wrapper} for
%     formatting. This is intended for font commands such as \cs{emph}.
%   
%   \item[\cs{bibcpstring\oarg{wrapper}\marg{key}}] 
%     Similar to \cs{bibstring} but the string is always capitalized.
%   
%   \item[\cs{bibxstring\marg{key}}] 
%     is a simplified but expandable version of \cs{bibstring}. Note that this
%     variant does not capitalize automatically, nor does it hook into the
%     punctuation tracker. It is intended for special cases in which strings are
%     nested or an expanded bibliography string is required in a test.
%   
% \end{compactdesc}
% 
% 
% The \verb+citetitle+ format is used to output the title field in citations.
%    \begin{macrocode}
\DeclareFieldFormat{citetitle}{#1}

% \paragraph{Formatting names and name lists}
% \label{sec:code:bib:formatting-namelists}
% 
% The following code morsels are taken from \file{biblatex.def} and modified.
% 
% The section employs special \pkg{biblatex} commands to (re)define or use
% macros in bibliography and citation styles.
% \begin{compactdesc}
% 
%   \item[\cs{newbibmacro\marg{name}\oarg{arguments}\oarg{optional}\marg{definition}}]
%     defines a macro to be executed via \cs{usebibmacro} later. The 
%     syntax and argument handling of
%     this command is very similar to \cs{newcommand} except that 
%     \begin{compactitem}
%       \item \meta{name} may contain characters such as numbers and punctuation
%       marks but no backslash, and
%       \item \cs{newbibmacro} issues just a warning message if the macro is
%       already defined, then falls back to \cs{renewbibmacro}.
%     \end{compactitem}
%   
%   \item[\cs{renewbibmacro\marg{name}\oarg{arguments}\oarg{optional}\marg{definition}}]
%     is similar to \cs{newbibmacro} but redefines \meta{name}.
%     If the macro is undefined,
%     \cs{renewbibmacro} issues a warning message  and falls back to \cs{newbibmacro}.
%   
%   \item[\cs{usebibmacro\marg{name}}] 
%     executes the \pkg{biblatex} macro \meta{name}, as defined with
%     \cs{newbibmacro}. If the macro takes any arguments, they are simply
%     appended after \meta{name}. \cs{usebibmacro} is robust.
%     
% \end{compactdesc}
% 
% 
% 
% This declares the output format of name lists to be used by \cs{printnames}.

% \subsubsection{The \protect\DTXclassname citation style}
% \label{sec:code:emisa-cbx}
% 
% \label{aut:cbx}
% 
% A citation style is a set of commands such as \cs{cite} which print
% different types of citations.  Such styles are defined in files with
% the suffix \file{cbx}.  The \pkg{biblatex} package loads the
% selected citation style file at the end of the package.  Note that a
% small repertory of frequently used macros shared by several of the
% standard citation styles is also included in \path{biblatex.def}.
% This file is loaded at the end of the package as well, prior to the
% selected citation style.
% 
% The \DTXclassname citation style is defined in the file \file{\DTXname.cbx}
% which is generated from the following code lines between the \texttt{<*cbx>}
% and \texttt{</cbx>} meta-tags.
% 
%    \begin{macrocode}
%<*cbx>
%    \end{macrocode}
%
%    \begin{macrocode}
\ProvidesFile{emisa.cbx}[2016/07/18 2.1.1 EMISA citation style]
\RequireCitationStyle{authoryear-comp}
\renewcommand*{\nameyeardelim}{\addspace}
%    \end{macrocode}
% 
% 
% \cs{DeclareRangeChars} configures the \cs{ifnumerals} and \cs{ifpages} tests.
% The setup will also affect \cs{iffieldnums} and \cs{iffieldpages} as well as
% \cs{mkpageprefix} and \cs{mkpagetotal}. The argument is an undelimited list of
% characters which are to be considered as range indicators. The regular version
% of this command replaces the current setting, the starred version appends its
% argument to the current list. The default setting is \{\verb&~,;-+/&\}, so
% strings like \enquote*{3--5}, \enquote*{35+}, \enquote*{8/9} and so on will be
% considered as a range.
% 
% Here we add the character \verb&f& to enable ranges like 
% ``123f'' and ``456ff''.
%    \begin{macrocode}
\DeclareRangeChars*{f}
%    \end{macrocode}
% 
% Here, the \DTXclassname citation style file \file{\DTXname.cbx} ends.
