Hi Michael, I don't understand. The Grammar Pool doesn't seem to have any say in the matter. I have a schema, say a.xsd and two documents a.xml and b.xml. The document a.xml references schema a.xsd and is valid according to the schema. The document b.xml has the same root element as a.xml but does NOT reference the schema and is not valid according to the schema. Assuming a.xsd is in the grammar cache, if I parse b.xml, the only calls to the implementation of GrammarPool are to retrieveInitialGrammarSet(). How does the Grammar Pool know whether or not a schema location hint was provided by the instance document? The only info that I get passed is "http://www.w3.org/2001/XMLSchema"; and http://www.w3.org/TR/REC-XML. One thing that may be relevant is that my schema don't have a target namespace. Cheers Russell Thamm

Grammar pool is an interface [1]. You're in control of what it returns. If you want it to only return a grammar if a schema location hint was provided by the instance document then you need to change your implementation of grammar pool to behave as such. > Cheers > Russell Thamm Thanks.
