I have to agree with Patrick here.  The mapping works if HTTP URLs
are used for namespaces  (if you're prepared to live with the
ambiguity problem that Patrick pointed out, and which Dan is
not concerned about).  However, it will not work in general for
other URI schemes.  For example, in a recent post I showed that
concatenation doesn't work if namespaces are given urn:publicid:
URIs that represent SGML "formal public identifiers".  This is
because these must end with a language identifier, e.g. "EN".
