There does not have to be anything there, having a unique label is
valuable enough in its own right. However, what we expect is that
format negotiation will be used to provide a number of different
definitions of the namespace. There would be human-readable ones
in HTML (and perhaps .txt and PDF). Once the RDF schema-WG has
specified schemas, they could also be provided. Other machine-
usable definitions could also be provided (I'm doing stuff with
Java class files).

You mean something like
<DC:Creator
DC:Scheme="http://www.loc.gov/???NAF.html">Twain, Mark
</DC:Creator>
I don't know that there will be URLs defined for all the schemes
we want to use, but creating them is a simple matter of work. :-/
