======Event Sub-Process======
* allow to handle an Event within the context of a given Sub-Processes or Process
* is a specialized Sub-Process that is used within a Process (or Sub-Process)
* when the triggeredbyEvent attribute of Sub-Process is true
* has no in-coming and out-going sequence flows
* MAY or MAY NOT occur while the parent Process is active, but it is possible that it will occur many times
* An Event Sub-Process MUST have one and only one Start Event
* has access to all data of the surrounding Sub-Process
* they cannot have attached boundary Events
* becomes initiated, and thus Enabled and Running, through the Activity to which it is attached
* There are two possible consequences to the parent Process when an Event Sub-Process is triggered:
** the parent Process can be interrupted (cancels execution of the enclosing Sub-Process, identified by an interrupting start event (if the isInterrupting attribute of its Start Event is set))
** the parent Process can continue its work (not interrupted, identified with an Non-interrupting Start Event) (enclosed runs parallel)
* If the parent Activity enters the state Completing, it remains in that state until all contained active Event Sub-Processes have completed.On the other hand the subsequent Activity of the Sub-Process with the Event Sub-Process will not be triggered until all Activities within the Sub-Process are finalized although the Event Sub-Process is already completed.
* there are special Event Sub-Processes

* A Compensation Event Sub-Process can recursively trigger compensation for Activities contained in its parent (see OMG spec example)
