REC-xml-names-19990114 has a section, "Namespace Constraint: Prefix
Declared", in which it is specified that "the prefix xml is by
definition bound to the namespace name
http://www.w3.org/XML/1998/namespace". As this recommendation goes,
things don't get any more explicit than that.

In general, this is correct. A given http-url is not, however, "just a name".

If this account is correct, then the notion of using http-url's was
misconceived. There are plenty of other uri schemas. Many of which
include domain names. The namespace recommendation should be careful to
either specify and to use uri's with the appropriate semantic or revise
the recommended semantic to match the uri which it specifies and uses.
