An application that supports a datatype should reject RDF graphs that do not write literals of that type properly. This would invalidate tons of existing RDF, so I don't think it's in the spirit of our charter: [[ For all new features, backwards compatibility with the current version of RDF is of great importance.

But that's just for OWL DL, right? Which isn't a proper extension of RDF Semantics anyway, right? How are ill-typed literals treated in the rest of OWL? Best, Richard
