Well, I guess I meant any kind of URL -- but since the proponents of
the contemporary view swear that there is no such class as URL anymore,
it would have been (for them least) a vacuous statement ;-)

Here here. But then, we seem to be a minority (though that doesn't
mean we're not right ;-)

Or at least to something other than a URL. (oops, there's that
vacuous statment problem again)

I fully agree. URLs are for accessing bits.
We need to use other URI schemes to augment the web in order
to achieve the semantic web.
The whole namespace bruhaha is directly due, I think, to
overloading the function of namespace URIs.
