Too strong. All we need is that its not for use as the datatype URI in an RDF typed literal. It would be fine to allow RDFS to reason about the class, for example. Yes, that is pretty much what my earlier suggestion amounts to, in practice. On another topic, the more I think about it, the better the idea gets of sticking to xsd:string for untagged literals and using rdf:text only for tagged ones. This seems to lead to a simplification in the spec for handling all the alternative function definitions as well.
