Your points about complexity are reasonable, however, XML + a DTD doesn't
really allow the same level of expressivity that RDF does, and it has no
semnatics, whereas an RDF description of a plugin can describe all sorts
of things without requireing a big complex DTD.
I suspect that if you did define it in XML you would end up reinventing an
unexstensible version of RDF lacking the tool support that RDF has.
