It appears I've referred to "definition" during this topic, which I should have been referencing "description". I hope that hasn't confused the issue too terribly to make it impossible to reply to this. To restate, only a few of the node instances in jpdl-3.2.xsd allow for a description element. I submit that they should all allow description, since description is a member of the node superclass. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4031551#...
