 * @class CompExtension
 * @sbmlbrief{comp} Base extension class for the package.

 *
 * @class CompPkgNamespaces
 * @sbmlbrief{comp} SBMLNamespaces extension for the package.
 *
 * @htmlinclude not-sbml-warning.html
 *
 * There is currently exactly one namespace defined for the Hierarchical 
 * %Model Composition package:
 * @c "http://www.sbml.org/sbml/level3/version1/comp/version1".  Despite 
 * referencing SBML Level&nbsp;3 Version&nbsp;1 explicitly, this package 
 * (and all such packages) can be used without change in SBML Level&nbsp;3
 * Version&nbsp;2 documents.  The only caveat is that features of the SBML 
 * Level&nbsp;3 Version&nbsp;2 specification that were not present in 
 * Level&nbsp;1 may not be used by constructs from the Hierarchical %Model 
 * Composition package.  The most relevant restriction this implies is that 
 * if a Level&nbsp;2 SBML element has an "id" attribute that was newly added 
 * in Level&nbsp;2 (when "id" was added to SBase itself), an SBaseRef "idRef" 
 * attribute may not reference it, and it must continue to use the "metaIdRef" 
 * attribute instead.
