Extensibility can be viewed as error handling: an unrecognized attribute in a normal container is known bad, but in an extension-point container the application can search for a newer version of the same namespace or try to resolve a different namespace,  Successful resolution allows the attribute to be recognized and validated, unsuccessful raises the validation error.

I don't know how XML treats _namespace="##other"_, but it might require the specified namespace to resolve before validation succeeds.
