Thanks for the reply / confirmation. More comments and questions in-line...

I think that is what DocumentBuilderFactory.setValidating(boolean) is 
supposed to do, and, to an extent is doing (as parser does try to validate 
the elements as they are encountered). The JAXP only supports 
setFeature(String, Object).

This does work, but is not JAXP compliant.

What really appears to be occurring is that the schema location is simply 
being ignored - as I can put anything in the noNamespaceSchemaLocation / 
SchemaLocation attribute and get the same results. I figured I would at 
least get an error if the schema document couldn't be obtained.

Should an error be thrown if the document referenced by the URI can't be 
obtained? Is this a bug in Xerces or am I the one with coding?
