You sound bitter about something.  Don't worry, it's really not all
that serious.

The fact that the XML Infoset is hardly used outside W3C XML Schema,
and that the XPath data model is far more common, and that focus on the
serialization is even more common than that is a matter of everyday
practicality.

And oh by the way, this thread is all about *your* customer's
complaining.  And your response is to give them your philosophical take
on XML.  Doesn't that contradict what you're saying above?

Oh never mind.  You posted something misleading, and I posted another
point of view.  I know you're incapable of any disagreement that
doesn't devolve into a full-scale flame-war.  Sometimes I have time for
that sort of thing.  This is not one fo those times, so this is
probably where I get off.
