 * @class LayoutExtension
 * @sbmlbrief{layout} Base extension class for the package.

 * @class LayoutPkgNamespaces
 * @sbmlbrief{layout} SBMLNamespaces extension for the package.
 *
 * @htmlinclude not-sbml-warning.html
 *
 * There is currently one possible namespace defined for the Layout
 * package: 
 * "http://www.sbml.org/sbml/level3/version1/layout/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 Qualitative Modeling
 * package.  The main restriction this implies is that the GeneralGlyph may
 * not reference any SBML element by its "id" attribute if that element would
 * not have had an "id" attribute in Level&nbsp;3 Version&nbsp;1.
