Agreed. The point of this feature suggestion is to make it more like the existing syntax for other events. Coordinates are not part of other events, so including them here doesn't do what the OP was wanting. The event should be done as hixxy showed. Everything else should be in the event, just like with any other kind of event.
I'm all for changing the unusual events to work like the rest of the events. Mouse and CTCP are two of these that really would be nice to see changed.
