The RDF/XML grammar does not deal with namespaces. The RDF namespace section is a set of URI-refs, and I don't want to confuse with (set of URI-refs) versus (XML namespace). I want some grammar terms for a set of legal URI-refs, at certain points. In this case the restrictions are that every legal URI-ref is allowed, bar a few terms that we have to forbid. "anyURI except from the RDF namespace" I feel is not as precise as "anyURI except for these ones" Re: likely for error, sure, but we can fix that. You pointed out some problems. Dave
