We believe that the hard coded references to XML 1.0 version 2 in: http://www.w3.org/TR/rdf-syntax-grammar/ and http://www.w3.org/TR/rdf-concepts/ and to Unicode 3.0 in http://www.w3.org/TR/rdf-syntax-grammar/ and http://www.w3.org/TR/rdf-concepts/ are unduly restrictive. We believe that they should normatively refer to the generically latest versions of both standards. Implementations that do not wish to update to the latest versions of those standard could indicate their conformance profile by saying "Supports RDF(RDF/XML) with Unicode 3.0 and XML 1.0 version 2". Since, technically speaking, such implementations must reject documents or models which, e.g., use characters only in Unicode 5.0 this conformance message seems reasonable. It also frees implementations to be conforming while accepting extended documents. If we have missed other places with hard code references to particular versions of XML and Unicode, we think they should be updated too. Cheers, Bijan Parsia, on behalf of the OWL working group. P.S., CCed to interested parties suggested by Ivan Herman.
