Sorry -- can't let that one slide.  URNs are quite useful without any
retrieval architecture.  In fact, the retrieval architecture is the
only thing which is unnecessary, since ANY query or search system is
capable of serving as a retrieval architecture (including grep).
Furthermore, the binding of URN scheme to retrieval architecture can
be made at any time by the client, so whether or not a retrieval
architecture exists at the current time should be irrelevant, unless
someone screws up the URN by including the retrieval architecture in
the identifier.
