I'll try to make a more formal list of what I see as the results of the consensus at the first meeting on this issue. 1. The grammar will be corrected to require namespace-qualified attributes for RDF concepts [leaving aside for now how the grammar will be expressed]. Namespace prefixes MUST be used on RDF attributes. 2. Existing parsers MUST accept the about, id etc. attributes in unqualified form on input but MUST NOT emit them on output. 3. The unprefixed attributes are deprecated and MAY be forbidden in future versions of the syntax. Replying to the W3C team comments in http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Apr/0047.html [[1. The grammar in section 6. of the M&S spec: http://www.w3.org/TR/REC-rdf-syntax/#grammar should be changed so that all of the RDF attributes (e.g. about, resource, etc.) are qualified with a RDF namespace. ]] This was agreed and I think covered in items 1-3 above [[2. Text along the lines of the following should be added to the M&S spec: All elements and attributes in RDF must be namespace qualified ]] I felt the consensus was that the elements part of the above text was not quite right (since elements can have default namespaces). The grammar does need correcting here to reflect that so another item: 4. The grammar must be corrected to allow non-namespace qualified RDF elements when a default XML namespace is defined (xmlns="..."). Dave
