Currently, we use WSDLs to describe the Petals services, but our WSDLs are actually not conforming to the WSDL standard: there is no bindings that actually specify that Petals is used for transport and data.
It would make sense to introduce a binding (as with SOAP and HTTP,etc transports) for Petals.
This binding should be extensible so that a SE like BPMN or Camel could have its specific settings (note: is that actually the right place to specify implementation specific things such as the bpmn process or the camel route to use???).
It would be useful from a governance point of view, and we then could also introduce tools to ease the manipulation of WSDL.
This would go hand in hand with the effort to make Petals full-SOA.
