 * Revision 1.14  2003/12/23 21:50:36  peiyongz
 * Absorb exception thrown in getCanonicalRepresentation and return 0,
 * only validate when required
 *
 * Revision 1.13  2003/12/19 23:02:25  cargilld

 * Revision 1.12  2003/12/17 00:18:39  cargilld
 * Update to memory management so that the static memory manager (one used to call Initialize) is only for static data.
 *

 * first part of PSVI/schema component model implementation, thanks to David Cargill.  This covers setting the PSVIHandler on parser objects, as well as implementing XSNotation, XSSimpleTypeDefinition, XSIDCDefinition, and most of XSWildcard, XSComplexTypeDefinition, XSElementDeclaration, XSAttributeDeclaration and XSAttributeUse.
