"...it is very unclear why you would want to do this anyway...'

Just a thought really. Since a DTD or Schema is a roadmap to incoming XML, it would be nice if it could also be reused as a roadmap for outgoing XML (like an i/o filter). Granted, XSL/XSLT is definately a great solution, but on the downside, that means we have to write both a DTD AND an XSL/XSLT stylesheet for the outgoing transformed request. Or make the destination queue owner do it. :-) I was just thinking since we already have a DTD, why not use it again instead of having to create more files to take care and feeding of.

"You ought to end up with four "phases" in your application thusly -- read from queue, validate document, transform document, write to queue."

Probably 5 steps for the paranoid at heart; read from queue, validate, transform, revalidate against destination queue DTD, write to queue. :-)
