I would like to get away from using XSL at all (the original point of the task). The approach you mention could work, but if I was going to go down that route, I would be more inclinded to 1) Create a MCF XSD and deprecate the DTD 2) Eliminate the problematic elements from the *-ds.xml deployment (ie MBean definitions) that get in the way of making the unmarshalling a simple process, or at least find someway to work around this. This was actually my initial approach but the MBean definitions inside the *-ds.xml got in my way. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4022626#...
