	Actually, if you take my XMOP project which serializes COM/IDL described
and Java objects into a DOM interface, and bolt it onto eXcelon, this is
pretty much exactly what this would do. XMOP uses either Java reflection or
COM typelibraries (which are compiled IDL and are close but not quite full
fidelity to MIDL itself), and serializes the object into either a DOM or an
XML stream.
