I do want it but in formally controlled way like you describe (without parsing the string of course ;-)) and not by comparing the xml of a pd. So a patch that does what you describe would be welcome. The thing is that it is not a simple patch. Requires db changes, so it is only possible in a 3.3 release. Besides that, it requires good tests for backwards compatibility and maybe conversion. If Argo516 wants to build a patch like that he/she is more than welcome. btw. did you know jbpm supports custom namespaces in the pd? You could have used that and use real xml attributes....
