I wrote that draft kind of quickly in order to get it under the deadline
and start this discussion.
Correct me if I'm wrong here: so it is always the case that, in order
to parse some XML according to a DTD and the SYSTEM literal is a URI,
then I must have connectivity in order to download the DTD? In that
case, how are names for DTD standardized? I rarely see anyone related
to XML using a PUBLIC identifier. They all tend to use the SYSTEM id
as some sort of name instead.
I can easily deprecate assigning a URN to a DTD in this spec. But
it does raise the issue of what the suggested practice from the W3C is.

Whether you give up or not, people will start using addresses as names
whether its possible to do so or not.
