It would be nice if common interoperable representational types were
described in a way that could be leveraged across all the XML
activities, even those that do not use WSDL. Of course, if there wasn't
a way to define "foreign" types in XML Schema, working groups like ours
would be forced to come with their own "first class" definitions, but
that doesn't seem to be the case any longer.
