[Ron Daniel]  The biggest problem is that such identifiers
are the intellectual property of particular standardization
and maintenance bodies. They would probably be somewhat
miffed if we start having our way with their property.

There is an RFC that hypothesizes URN namespaces like
urn:isbn and urn:issn. But those will not be standardized
without the permission of the relevant organizations.

[Ron Daniel]  Yes, such a thing should be developed. However,
I am not aware of any active W3C working group that could take
this up.

One thing to keep in mind is that there are degrees of equivalence.
