RE: RDF/XML does not support numeric terms [was: RE: 8 points for GRDDL (output other than RDF/XML?)]

Sampo,

Misha's point is that since the RDF/XML syntax relies on *QNames* to
represent URIs, and *QNames* do not allow a numeric part as the local name,
then RDF/XML does not support his schemes. It's one of the many examples of
inappropriate use of QNames in different languages, and was the whole reason
I have proposed CURIEs [1].

An initial motivation for CURIEs (which comes out of working with Misha and
the IPTC) is on my blog [2]. A more detailed explanation in the context of
discussion on the themes covered by CURIEs is in a later post to this list
[3].

Regards,

Mark
