I'm very interested to know how this turns out; I see that
the chair proposes to decline our request,
http://www.w3.org/2000/12/xmlschema-crcomments.html#datatype-uri
but I don't see the final disposition/wg-decision.
www-rdf-logic and joint-committee folks, if you have an opinion
about whether #xpointer(id("date")) is acceptable, or whether
it's an undue implementation burden, compared with #date, please
speak up now.
The implementation burden is something like what Sandro described:
[[[
We can solve this easily for the standard datatypes by putting all
the classes in some ontology, publishing the classes you've been
using (and using a nicer identifier syntax).
]]]
