Many data providers don't use oai-identifier schema, in extreme cases
for example dispute (http://dispute.library.uu.nl/cgi-bin/oai.pl) uses numbers
such as 3465,3481. It'll be extremely hard (or impossible) to develop a
resolver for this kind of identifier.

I had same problem in DP9, I think the proposed PURL OAI schema
(http://www.dlib.org/dlib/july03/young/07young.html) also needs to solve
the same problem.

Probably some actions can be taken to ensure the possibility of a general
