 Re: XTOPP?
XTOPP (and XTUSK) are not waypoints, or approaches.
Seems that flightaware is using this is to mean "through" TOPPS, dropping the final letter of the waypoint as it likely has five letters fixed for waypoints.
You'll see this on any westbound transatlantic flight listing. Eastbound flights usually list the entire filed route, even the landing STAR.
