We changed the behaviour due to streaming validation. Keyrefs


  maybe the line of the reference can be saved at the same time of the
value, that's what I did for ID in DTD validation when streaming. And
it is sufficient for the error report you don't need to keep a pointer
to the node.

This would be anchored in _xmlSchemaPSVIIDCNode. We still have a
"node" field there - a remainder. So remove "node" and add "int line"?

By the way, I tested this with Xerces-J 2.7.1:

keyref.xml:7,12: (Error) Key 'keyref' with value 'test' not found for
identity constraint of element 'ELEMENTS'.
(the line number points to the end tag of ELEMENTS by the way) 

Xerces uses the same mechanism as we do.

  We can certainly improve over xerces user-friendlyness ;-)

OK, I'll try.
