PropertyStatus enhancement - PropertyChanged routed event

Hi,

I've modified the PropertyStatus control to have a PropertyChanged routed event.  I think this would help enable some useful things; my motivation was to run an animation ONLY when the BO property has changed.  Here's the code:

    private static readonly RoutedEvent PropertyChangedEvent =
        EventManager.RegisterRoutedEvent(
          "PropertyChanged",
          RoutingStrategy.Bubble,
          typeof( RoutedEventHandler ),
          typeof( PropertyStatus )
      );


    public event RoutedEventHandler PropertyChanged {
        add { AddHandler( PropertyChangedEvent, value ); }
        remove { RemoveHandler( PropertyChangedEvent, value ); }
    }

And then, the souce_PropertyChanged event handler looks like this:
            if ( e.PropertyName == Property || string.IsNullOrEmpty( e.PropertyName ) ) {
                UpdateState();
                RaiseEvent( new RoutedEventArgs( PropertyChangedEvent, this ) );
            }

Thanks!
Andy
