When I use the GPX 1.1 format the route corresponds much better with the track (intended route) than with GPX 1.2 Unfortunately, all shaping points become visible in the list of the route and the via-point cannot be distinguised. This way you have to search for the via-points by hand and mark them in the route.
In conclusion, both GPX 1.1 and GPX 1.2 have their (own) draw backs
