I'd be interested in more information on this last comment.
Also I'd like your opinion on the maintainability of this route. It
seems to me that once you generate the DTD and distribute it to your
business partners, internal customers and so forth, it takes on a life
of its own separate from the UML model. Changes must now be considered
in terms of backwards compatibility at the XML, not UML level.
Documentation is mostly at the XML level, etc.
