Although having two different identifier systems is a problem in theory, in
practice it appears to me that at this point there are only a handful (a
small number) of schemas that have identifiers of both styles.
Could we perhaps:
1. precisely enumerate those that have the multiple identifiers.
2. come up with a procedure whereby when a schema identifier is needed:
- First check if one already exists.
- If it does, then it should be used, both by SRU and OpenURL,
regardless of which syle it is.
- if it does not, then assign an identifier: OpenURL style if it is
(initially) for OpenURL use, SRU style if for SRU, and both registries add
it.
