And I can add another. JDOM at least tries to do this, though
currently that code is broken. And I'm working on a third myself,
which is why I bumped across this.
I agree that URI conformance should be a requirement. I think it
could probably be made so in Namespaces 1.1 without any great effort.
The simplest way would be to add a namespace constraint specifying
that the value of a namespace declaration attribute must be a legal
RFC 2396 URI reference.
The question for me is whether this is a small enough and obvious
enough change that it could plausibly be made an erratum to 1.0. A
little to my surprise, Dare pointed out one major public case
(WebDAV) where the actual namespace name was in fact not a URI
reference.
Julian Reschke pointed out that there was a different loophole WebDAV
could use, based on a future version of RFC 2396. Of course, the
namespaces spec references 2396 only, not 2396 and its successors. :-(
Not that the namespaces errata are models of backwards compatibility
and small changes, but I do prefer to be very conservative in what's
classified as an erratum. I feel this change is just a little too big
to be justified as an erratum. I think it needs to wait for
Namespaces 1.1.
