It makes lots of sense that OOP folks would have difficulty with this,
given that OOP has made a virtue of binding data and behavior.  (OOP's
XML integration problems strike me as eerily familiar to its RDBMS
integration problems, where a similar separation is popular.)

Trying to explain that mixing data and processing is fine while you're
processing the data and awful when you're transferring the information
between dissimilar systems doesn't always seem to go over well.
Programmers seem to put a lot of effort into abolishing "dissimilar"
instead of taking advantage of the separation.  At least that's the
lesson I've seen in most of this Web Services stuff...
