Right and all I am saying is that by picking the encoding of
the URN wisely (with some URI type information) it makes the whole
thing a bit more useful.

One thing to consider is how useful is a document when the network
isn't available. If I download a document to my laptop to read
on a plane, do I want no clue as to references until I can
plug the things in and get URN translations.
I understand what you said about there not being a standard for
citations and there might be different types. However, part of the
problem is that the tools to standardize upon aren't yet. When they
are there I would bet you start seeing a lot of local standards biased
toward URNs, because they are the most longstanding.
