yeah, this seems to work, but does anybody know if there is a better way?

It looks like errors are ignored if the schema wasn't resolved.  Is this 
the way to do it?

Tell me something I don't already know.  I want validation if there is a 
schema specified, no validation if there is not.

The element declaration is required (from your error message)
http://www.w3.org/TR/xmlschema-1/#cvc-elt

and validation is required for minimal conformance:

Re: [JBoss-dev] optional schema validation

2006-03-20 Thread Bill Burke

I'm looking at how we do parsing and looking at 
XmlFileLoader.LocalErrorHandler.


It looks like errors are ignored if the schema wasn't resolved.  Is this 
the way to do it?
