Added an initial skeleton for indentity-constraints. This is all defined
* xmlschemas.c include/libxml/schemasInternals.h: Added an initial skeleton for indentity-constraints. This is all defined out, since not complete, plus it needs support from other modules. Added machanism to store element information for the ancestor-or-self axis; this is needed for identity-constraints and should be helpfull for a future streamable validation. * include/libxml/xmlerror.h: Added an error code for identity-constraints.
