                               ModuleRevisionId mrid,
                               ModuleRevisionId dynamicConstraint,

### Method Detail

#### transformInstance

    public static DependencyDescriptor transformInstance(DependencyDescriptor dd,
                                         Namespace ns)

Transforms the given dependency descriptor of the given namespace and return a new dependency descriptor in the system namespace. Note that exclude rules are not converted in system namespace, because they aren't transformable (the name space hasn't the ability to convert regular expressions). However, method doesExclude will work with system artifacts.

Parameters:
  `dd` -
  `ns` -
Returns:

#### transformInstance

    public static DefaultDependencyDescriptor transformInstance(DependencyDescriptor dd,
                                                NamespaceTransformer t,
                                                boolean fromSystem)

Transforms a dependency descriptor using the given transformer. Note that no namespace info will be attached to the transformed dependency descriptor, so calling doesExclude is not recommended (doesExclude only works when namespace is properly set)

Parameters:
  `dd` -
  `t` -
Returns:

  A Map instance containing all the attributes and their values.

#### getExtraAttribute

    public java.lang.String getExtraAttribute(java.lang.String attName)

  `getExtraAttribute` in interface `ExtendableItem`
Parameters:
  `attName` - the name of the extra attribute to get. This name can be either qualified or unqualified.
Returns:
