It would not be incorrect that a resource has more than one URN,
or more precisely, that the same thing (identical) is known by
more than one URN. I publish a work, give it a URN from my
name space. I sell the copyright to you; you publish *the exact same
thing* and give it a URN from your name space. Nothing wrong,
or even unexpected, with that.

URNs as presently described are not uniform titles, nor do I think
this group wants them to be, from reading the discussion, because
a uniform title must be supported by more bibliographic overhead
than anyone wants to deal with right now. Nothing wrong with
that, either.
