Simple
h3. Purpose
* Allow the listener to receive only the root event of a system change.
h3. Situation
* In a telecommunication environment, application are routed through a network of switched and miscellaneous communication equipments. When a switch goes down, applications must be routed through another switch, but a crew has to be dispatched to fix the faulty equipment. To do that, we must be able to capture all system events, but to only forward the root event (which switch is down) to the service crew.
