Concerning about :
http://www.topografix.com/gpx/1/1/Waypoint : wpt represents a waypoint, point of interest, or named feature on a map.
Route : rte represents route - an ordered list of waypoints representing a series of turn points leading to a destination
Track : trk represents a track - an ordered list of points describing a path.
In general, most gps app. deal with waypoints, routes, and tracks.
But, Locus does not have the concept of 'Route'.
In Locus, I think that the concept of Track are used to be mixed with Route
Frankly speaking, I am very confused with that.
Why don't you add the concept of Route in Locus ?
