How do XML NameSpace aware processors react to NS definations?

any validation.

Assuming that the parser is a validating NS aware parser,
I was wondering what other validations could the parser perform.

* It would be difficult for the parser to validate the content model,
attributes of all the prefixed names against their definations in the DTD
since the Namespace URI only signifies a unique identifier, nothing more.So
validating prefixed names in the way given above would be difficult.
Am I right?
Then what other validations are left which are relevant to namespaces?
