xml public identifier

Your right, in XML the PI can be a URL or whatever.  PI's historically
had some of the same issues as namespaces.  History always repeats
itself.  There wasn't a formalized way to implement PI's in SGML
and the result was that they were implemented differently in different
software.  It wasn't until OASIS  published Technical Resolution 9401
that moved vendors to support PI's uniformly.

I believe something like TR 9401 is needed for XML.
