DOMNormalizer used for a xsd document

[Dick Deneer]

I am using the DOMNormalizer to validatie instance document against  
DTD or  XSD.
I noticed that this even works when the instance document itself is  
an xsd. You can give  http://www.w3.org/2001/XMLSchema.xsd  as the  
schemaLocation and the document will be validated without problems.  
PSVI information will be added to the DOM. So far the behaviour great  
and exactly what I need (DOMError locations, psvi).

But the checking that is done to the schema is not as strict as done  
by a real GrammarParser.
But to the grammarparser I can not pass a DOM. Is there a solution  
for my problem. ?
