 * $Log: SchemaGrammar.hpp,v $
 * Revision 1.15  2004/01/29 11:52:31  cargilld
 * Code cleanup changes to get rid of various compiler diagnostic messages.
 *
 * Revision 1.14  2003/12/17 00:18:40  cargilld
 * Update to memory management so that the static memory manager (one used to call Initialize) is only for static data.
 *
 * Revision 1.13  2003/11/14 22:35:09  neilg
 * changes in support of second phase of XSModel implementation; thanks to David Cargill
 *
 * Revision 1.12  2003/11/12 20:35:31  peiyongz

 * Implementation of Serialization/Deserialization
 *
 * Revision 1.9  2003/09/22 19:49:03  neilg
 * implement change to Grammar::putElem(XMLElementDecl, bool).  If Grammars are used only to hold declared objects, there will be no need for the fElemNonDeclPool tables; make Grammar implementations lazily create them only if the application requires them (which good cpplications should not.)

 * Schema: Unique Particle Attribution Constraint Checking.
 *
 * Revision 1.8  2001/07/31 15:27:10  knoaman
