[OAI-implementers] OAI Identifiers

If I recall, when the oai identifier scheme was proposed it was felt that
benefit of a layer of abstract permitting persisitence of ids even if URLs
change outweighed the possible registration difficulties. Note that the
<!-- * A "repositoryIdentifier" that is a unique identifier for a -->
<!-- repository. Its uniqueness will be tested as part of a -->
<!-- registration process. The repositoryIdentifier is case -->
<!-- sensitive and may contain the characters [a-z]|[A-Z]|[0-9] -->
<!-- e.g. arXiv, VTETD. -->
Note also that OAI-PMH does not mandate this scheme and not all registered
repositories have chosen to use it.
