Pretty awful to program in, wouldn't you think? ;) Have a look at JavaML to see
how a OO language expressed as XML looks.. it's not pretty.

I wrote something like this.. you could embed declarative XML statements in
regular code, eg:

<debug level="1">This is a debug statement</debug>

Then a preprocessor converted that <debug> statement to real code for the
target language. New tags can be added by writing XSLT stylesheets.

Code available on request; gory details available at

How about Java bytecode?
