62 * Revision 1.5  2003/11/28 20:20:54  neilg
63 * make use of canonical representation in PSVIAttribute implementation
64 *
65 * Revision 1.4  2003/11/27 06:10:32  neilg
66 * PSVIAttribute implementation
67 *
68 * Revision 1.3  2003/11/06 21:50:33  neilg
69 * fix compilation errors under gcc 3.3.

71 * Revision 1.2  2003/11/06 15:30:04  neilg
72 * 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.
73 *
74 * Revision 1.1  2003/09/16 14:33:36  neilg
75 * PSVI/schema component model classes, with Makefile/configuration changes necessary to build them
