Request a custom command. Results are returned via MCCEExtensionObserver . Many service-ids may map to same plug-in. Request-id is used for plug-in internal id of the request. Replies use also a service-id, but if e.g. one plug-in uses two service-ids 10 and 11 then request might use 10 and reply use 11.
