\brief A protocol transition specifies a legal transition for an operation. Transitions of protocol state machines have the following information: a pre condition (guard), on trigger, and a post condition. Every protocol transition is associated to zero or one operation (referred BehavioralFeature) that belongs to the context classifier of the protocol state machine.
