Hi! Since the change of rev802821 (null instead of empty string for namespaces) I'm getting NullPointer Exceptions for my testcases (coming from Render.java), they are not specific to my code (as far as I can see) but don't come up with the test-cases of vysper-core.
Why is it better to return a null? If a XML element has no namespace declared, it lies in the "empty" namespace, so a empty string would conform to the standard. If there is no particular need for the change, I'd rather revert it. Thanks, Michael
