LOL, so would I!  :-)

Yes, XML was not designed with particular applications in mind. In fact,
it was designed bottom-up.

Because XML parsers are available in every language built-in, while LISP
and scheme parser are not ubiquitous, have less good internationalization,
 encourage rather than discourage the addition of processing, and does not
have validation languages.

This is high-order analizing.
