Forcing schema validation

[i.am.thor]

Does anyone know of a way to force validation of an XML file if the
schemaLocation attribute is not set in the document? For example, I'm
trying to use the loadGrammar() function of the xerces parser to force
it to validate foo.xml against foo.xsd, even though foo.xml does not
contain the schemaLocation attribute. The function returns OK, but
subsequent calls to parse() do not actually validate against the
grammar.

Sanity check: Did you remember to turn on the schema validation Feature?
Xerces defaults to running in nonvalidating mode.

There are also Properties that control where schemas will be retrieved
from, which might be worth looking at
