The Internet media type system doesn't have a general concept of  
validity, so I'm uncomfortable linking XML Schema validity to  
format-specific constraints in this manner; implementations may  
interpret them in different ways, causing interoperability problems.

A safer approach would be to stay silent on the relationship between  
schema validity and media types, and forcing any errors to the  
application level.
