* xmlschemas.c: The schema parser will stop if components could
  not be resolved. This is not conforming to the spec but for now
  will avoid internal errors during type fixup and content model
  creation. Restructured inclusion/import of schemata: this avoids
  duplicate, self and circular inclusion. Chameleon includes are
  still workarounded. Added restriction to disallow references to
  non-imported namespaces. Corrected parsing of <group>.
* result/schemas/bug167754_0_0*: Added a missing test result.
