This is true and important to keep in mind, but I think Wolfgang also
has an important point.
The issue at hand is precisely what sort of relation there is between
the world of XDM and the world of XML over the wire, or in the black
box at the other end.
As far as that goes, I think AC is onto something in writing:
I would simply like to also highlight some more "qualitative"
aspects of XSLT type handling, including the support for implicit
typing, the fact that explicit typing can be used as required, the
fact that types can be expanded, defined, and checked in a formal
process (e.g. schema), as well as the good support for type casting,
detection, and conversion.
One of the important contributors to the success of XSLT 2.0 is that
one can still work quite productively with fairly weak typing or with
typing that is strong only where it needs to be.
Not that I know anything about it, but my guess is that while this
doesn't make the issue of mapping type systems to one another
disappear, in practice it often means it is somewhat less critical
(and less onerous) than it might be.
Cheers,
Wendell
