Changes since version 20061115

* The message element was rejected, reporting that it is not allowed - fixed.

  now it checks against all the pattern constraints because Relax NG specifically 
  require this behavior.
* Update Xerces to Xerces 2.9.0
* Use the EntityResolver if specified in the AutoSchemaReader class.
