Right, I would not generalize URI-URI rewriting, but keep the
catalog rewriting to public, system, and whatever other functional
area on which we have consensus (I don't feel the strong need for
any, but I might be able to live with some given some convincing
arguments).  Let's not make the mistake some W3C XML-related specs
have made and over-complicate our first pass.  I'd like to see us
come up with something which is pretty much just TR9401.  If we
get agreement and implementations, and experience shows there is
a widespread need for more, then we can later consider adding them.
