Ummm.... of which type: a name (URN) or as a network named location (URL)?

The PUBLIC identifier, as you know, can have interesting 
information in it that has nothing to do with dereferencing 
a representation from a resource over a network protocol. 
Are you saying the URI in the PUBLIC id would point to a document 
for getting that information?

That would also mean that nothing can be done with XML unless 
it is done "on the web".  PUBLIC IDs are a way to hook up 
to other systems.  You would be legislating away that right.

You know all of that, so this must be a lead in to the 
'is the web the universe or just a network of documents 
and other ports of call' thread.

IMHO it would have been better to decree that in XML the public id,
rather than the system id, must be a URI.
