OTOH it might be that the job of saying "What are the associated for this namespace?" and "What is the local meaning of this system id or public id?" are actually quite orthogonal, and should be handled by separate mechanisms. > As an aside, I think the difference between PUBLIC IDs and NS URIs > is not important.
