Just require URLs

That string is not syntactically a URN. Please see RFC 2141. It is quite
explicit:

All URNs have the following syntax (phrases enclosed in quotes are
REQUIRED):

                     <URN> ::= "urn:" <NID> ":" <NSS>

If I'm right on this issue (and what room is there for dispute) and you
are right that it cannot be interpreted as a URL in the context that we
are discussing (more subtle but still, I think right) then you must agree
with me that this is not a URI *of any sort* and thus in violation of the
namespaces specification which is both clear and consistent in this
regard.

"Silence," wrote Melville, "is the only Voice of God." The assertion,
like its subject, cuts both ways, negating and affirming, implying both
absence and presence, offering us a choice; it's a line that the Society
of American Atheists could put on its letterhead and the Society of
Friends could silently endorse while waiting to be moved by the spirit
to speak. - Listening for Silence by Mark Slouka, Apr. 1999, Harper's
