......................................................................
(Schema) Change ConnectionRef actions to work on a single connection
This was the original intention of the API. The reason we started
supporting multiple connections in a single call is because of the
overhead inherent in XML-RPC. The new API can multiplex calls and has
practically no overhead per call.
Also, refID is not an UUID
