David, in the F2F you mentioned the need for a new element to contain industry specific business process identifiers such as a RosettaNet PIP identifier. Could this be done with Service/Action where the Service would be something like RNet and the Action something like PIP3A1 (Request Quote)? <eb:Service>urn:services:RNet</eb:Service> <eb:Action>PIP3A1</eb:Action> Regards, David Fischer Drummond Group.
