That is one explanation.   However:

1.  No one has stated a requirement that the name actually 
be an ID.  A name will do.  (see elliotte).  If a 
name will do, this is a nameloc and there is not a gaping 
hole in the architecture.

2.  If that is not the case, and it must be an ID, then 
what the xml:id proposal does is begin to marginalize 
the use of DTDs.

Not without a bounded scope, Jonathan.  The days 
of the freedom of the XML core groups to obscure 
by misdirection such notions are over.  Never Another 
"Namespace Is Just A Disambiguating String" ploy.

All requirements up front, clear, and signed. 
Otherwise, no change.  It costs too much to 
allow the children to play in the design these days.

The whole point of xml:id is for documents which are well-formed. All valid
XML documents are valid with respect to a DTD which can indicate IDs.

Right, but there is no need to add xml:id to documents which are associated
with a DTD, the entire reason for existence is those XML documents without a
DTD. So yes, you can shoot yourself in the head, but doing so is not
recommended :-)
