   Every participant should implement a handler class that implements the AutomationCompositionElementListener interface

 These method from the interface are implemented independently as per the user requirement. These methods after handling the
 appropriate requests should also invoke the intermediary's publisher apis to notify the ACM-runtime with the acknowledgement events.
