Good point about the editing with a separate editor - from a programmatic perspective embedding the task forms is better, but from a user perspective it would probably just be a pain in the ass. As far as the separate element goes though, I think it's just as easy (or easier) to parse without it - the GPD (or anyone else) need simply iterate the child elements of the "transition" element, as opposed to finding a child of "transition" called "edge" in the GPD namespace, and iterating the child elements of that. I'd say it's even easier this way. With DOM it's less traversal, and with SAX or StAX it would result in a simpler state machine.
