 * Revision 1.9  2003/12/02 01:27:01  knoaman
 * Properly set fAnnotation data member
 *
 * Revision 1.8  2003/11/25 20:37:40  jberry
 * Cleanup build errors/warnings from CodeWarrior
 *
 * Revision 1.7  2003/11/23 16:20:16  knoaman
 * PSVI: pass scope and enclosing type during construction.
 *
 * Revision 1.6  2003/11/21 17:29:53  knoaman
 * PSVI update
 *
 * Revision 1.5  2003/11/14 22:47:53  neilg
 * fix bogus log message from previous commit...
 *
 * Revision 1.4  2003/11/14 22:33:30  neilg
 * Second phase of schema component model implementation.  
 * Implement XSModel, XSNamespaceItem, and the plumbing necessary
 * to connect them to the other components.
 * Thanks to David Cargill.
 *
 * Revision 1.3  2003/11/06 15:30:04  neilg
 * 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.
 *
 * Revision 1.2  2003/09/17 17:45:37  neilg
 * remove spurious inlines; hopefully this will make Solaris/AIX compilers happy.
