I want to be clear that I am not proposing the adoption of a "single
URI scheme", nor am I advocating "imposing" anything.  I have no doubt
that there will eventually be many different URN schemes in use.  I am
simply suggesting this as an IANA-registered URN scheme that can be used
right now for namespaces.
