Hmm... I guess I need to look into this harder. It is correct that we do not want to go towatd XML Revision 5 because of its changes to legal name characters. The entire XHTML suite of specifications is setting on Revision 4. If the updated namespaces spec relies upon revision 5.... I am not sure what the working group will want to do.

I will keep you all posted.

Hi Dan,

I noticed the same thing last week. Michael Hausenblas sent a message[1] to the RDF in XHTML mailing list. The conclusion was that this is an error.

Cheers,

    No... I'm saying: the definition of Name in XML went
    from, roughly, "only prescribe characters" to "everything except
    disallowed characters". See http://cmsmcq.com/mib/?p=606
    for some relevant commentary.

    And NCName in the XML namespaces spec is defined in terms of
    Name from XML. and CURIE is defined in terms of NCName from
    namespaces.

    I tried to find a relevant test case in
     http://www.w3.org/XML/Test/
    but I got lost in the maze.


    XML and Namespaces got updated, but evidently that didn't
    complete until just after RDFa was cooked.
