RetryTaskTimerHandler

This timer handler retries an escalated task. The handler and its timer need to be defined below the Process element. The name of the task to retry is specified in the additional attribute "task".

RunActionTimerHandler

This timer handler runs one or more actions on expiration. The actions can be defined using the sub element Action.

SkipUserTaskTimerHandler

This timer handler aborts the activated user task on expiration. It does not work with a task if it is not activated.
