Title: Disable XSD grammar caching

Grammar caching in Xerces uses namespace URIs as the identifying ID
for XSD grammars. Because DITA uses empty namespace, grammar caching
will fail because the first XSD parsed will be used for all documents,
regardless of topic type or XSD system URI.

Disabling grammar caching for XDS will reduce parsing speed, but will
enable using multiple schemas during one process run.
