/ Jonathan Borden <jborden@mediaone.net> was heard to say:
| Let me clarify. The problem with using a prefix:name in a standalone DTD is
| that nowhere within the DTD file is the prefix<->namespace mapping defined
| (i.e. akin to the "Prefix Defined" constraint). In an internal subset, the
| prefix, though used within the DTD, is defined within the document content
| (not necessarily just the root element).

Right, sorry. I misinterpreted your message. Basically, you're using
the PE trick to change prefixes on the fly.  Yes, that works, but it
still limits you to a single prefix. I remain tempted to implement
<?declare-namespace prefix="foo" uri="bar"?> in the DTD and
dynamically map the prefixes during validation.
