/*
* schemas.c : implementation of the XML Schema handling and
* schema validity checking
*
* See Copyright for the status of this software.
*
* Daniel Veillard <veillard@redhat.com>
*/
/*
* TODO:
* - when types are redefined in includes, check that all
* types in the redef list are equal
* -> need a type equality operation.
* - if we don't intend to use the schema for schemas, we
* need to validate all schema attributes (ref, type, name)
* against their types.
* - Eliminate item creation for: ??
*
* URGENT TODO:
* - For xsi-driven schema acquisition, augment the IDCs after every
* acquisition episode (xmlSchemaAugmentIDC).
*
* NOTES:
* - Eliminated item creation for: <restriction>, <extension>,
* <simpleContent>, <complexContent>, <list>, <union>
*
* PROBLEMS:
* - http://lists.w3.org/Archives/Public/www-xml-schema-comments/2005JulSep/0337.html
* IDC XPath expression and chameleon includes: the targetNamespace is changed, so
* XPath will have trouble to resolve to this namespace, since not known.
*
*
* CONSTRAINTS:
*
* Schema Component Constraint:
* All Group Limited (cos-all-limited)
* Status: complete
* (1.2)
* In xmlSchemaGroupDefReferenceTermFixup() and
* (2)
* In xmlSchemaParseModelGroup()
* TODO: Actually this should go to component-level checks,
* but is done here due to performance. Move it to an other layer
* is schema construction via an API is implemented.
