Identifies the MouseDown attached event.
Assembly: PresentationCore (in PresentationCore.dll)
Routed event identifiers are created when routed events are registered, and the result is stored as a field on the class that registers the routed event. These identifiers contain an identifying name, owner type, handler type, routing strategy, and a utility method for adding owners for the event. You often use these identifiers as parameters to event system methods, to identify a particular routed event.
