Correct me if I'm wrong, but I thought the difference between URN and
URL was, well, N and L. N is just a name, but L is a location.
Taking this back to the original context:

The URL, on the other hand, says they are the same thing, and then it
goes on to imply they exist in the same location. In this case, they
don't exist in the same location. If they did, they'd have the same
HREF and the additional attribute would be unnecessary. So using a
URL as a UID creates a false assertion.
