11.6.3 End Events

End Events provide a graphical marker for the end of a path within the Choreography.

Table 11.8 – Use of End Events in Choreography

Type of Event	Usage in Choreography?

None	Yes. This is really just a graphical marker since the sending of the previous
	Message in the Choreography is really the end of the Choreography. The
	Participants of the Choreography would understand that they would not expect
	any further Message at that point.

Message	No. A Message End Event, in a stand-alone Choreography, has no way to
	show who the senders or receivers of the Message should be. A
	Choreography Task should be used instead. Thus, a None End Event should
	be used as a graphical marker for the “end” of the Choreography.

Error	No. These are Throw Events and there would be no way to indicate the
	Participant that is the source of the Error.

Escalation	No. These are Throw Events and there would be no way to indicate the
	Participant that is the source of the Escalation.

Cancel	No. These are Throw Events. As with a Message Event, there would be no
	indicator as to who is the source of the Cancel.

Compensation	No. These are Throw Events. As with a Message Event, there would be no
	indicator as to who is the source of the compensation.

Signal	No. These are Throw Events. As with a Message Event, there would be no
	indicator as to who is the source of the Signal.
