/**
 * \page maybe_metadata_reads Functions with No Access Property List Parameter that May Generate Metadata Reads
 *
 * \ingroup GACPL
 *
 * Currently there are several operations in HDF5 that can issue metadata reads
 * from the metadata cache, but that take no property list. It is therefore not
 * possible to set a collective requirement individually for those operations. The
 * only solution with the HDF5 1.10.0 release is to set the collective requirement
 * globally on H5Fopen() or H5Fcreate() for all metadata operations to be
 * collective.
 *
 * The following is a list of those functions in the HDF5 library. This list is
 * integral to the discussion in the H5Pset_all_coll_metadata_ops() entry:
 *
 * <pre>
 *
 * H5Awrite()
 * H5Aread()
 * H5Arename()
 * H5Aiterate2()
 * H5Adelete()
 * H5Aexists()
 *
 * H5Dget_space_status()
 * H5Dget_storage_size()
 * H5Dset_extent()
 * H5Ddebug()
 * H5Dclose()
 * H5Dget_create_plist()
 * H5Dget_space()   (when dataset is a virtual dataset)
 *
 * H5Gget_create_plist()
 * H5Gget_info()
 * H5Gclose()
 *
 * H5Literate()
 * H5Lvisit()
 *
 * H5Rcreate()
 * H5Rdereference2()   (when reference is an object reference)
 * H5Rget_region()
 * H5Rget_obj_type2()
 * H5Rget_name()
 *
 * H5Ocopy()
 * H5Oopen_by_addr()
 * H5Oincr_refcount()
 * H5Odecr_refcount()
 * H5Oget_info()
 * H5Oset_comment()
 * H5Ovisit()
 *
 * H5Fis_hdf5()
 * H5Fflush()
 * H5Fclose()
 * H5Fget_file_image()
 * H5Freopen()
 * H5Fget_freespace()
 * H5Fget_info2()
 * H5Fget_free_sections()
 * H5Fmount()
 * H5Funmount()
 *
 * H5Iget_name()
 *
 * H5Tget_create_plist()
 * H5Tclose()
 *
 * H5Zunregister()
 * </pre>
 *
 * In addition, \b most deprecated functions fall into this category.
 *
 * The HDF Group may address the above limitation in a future major release, but
 * no decision has been made at this time. Such a change might, for example,
 * include adding new versions of some or all the above functions with an extra
 * property list parameter to allow an individual setting for the collective
 * calling requirement.
