Additional details can be provided using 15// the details argument. These details (if provided) appear in the 16// ActivityTaskCanceled event added to the workflow history. Only use this 17// operation if the canceled flag of a RecordActivityTaskHeartbeat request returns 18// true and if the activity can be safely undone or abandoned. A task is considered 19// open from the time that it is scheduled until it is closed. Therefore a task is 20// reported as open while a worker is processing it.

The associated event attribute's cause 40// parameter is set to OPERATION_NOT_PERMITTED.
