The URN by itself does not supply the infrastructure to promote
availability, any more than the ISBN number, by itself, provides the
infrastructure of booksellers, libraries and other organizations that
allow us to ensure books are available even if the publisher is no

The URN descriptions so far have not, as far as I can see, explained
the motivation which will cause such a mechanism to arise and remain
supported for the length of time we normally associate with the
availability of physical scholarly artifacts.
