 * @class SBMLDocumentPlugin
 * @sbmlbrief{core} Base class for extending SBMLDocument in packages.
 *
 * @htmlinclude not-sbml-warning.html
 *
 * The SBMLDocumentPlugin class is a specialization of SBasePlugin
 * designed specifically for extending SBMLDocument.  All package
 * extensions must extend SBMLDocument to implement support for SBML
 * Level&nbsp;3 packages; these extensions can be subclasses of this
 * class or from a derived class of this class.
 *
 * All packages must additionally define a
 * required flag named <code>required</code>, which indicates whether 
 * that package's constructs can be used to change the core mathematics of the
 * <code>&lt;model&gt;</code> child of the <code>&lt;sbml&gt;</code> element.
 * If they can, this attribute must be set @c true, and if they cannot, this 
 * attribute must be set @c false.
