Hello,
I will have a better look into the documentation for implementing PTv2 for the next modifications I will do.
However, for the names of the stops, I do not agree. The names of the stops are now being changed to DIDOK in Switzerland, which is the same as the uic_name. Here is the timetable of bus 123 which displays names with DIDOK. I does not make sense to leave hundreds of stops called "Dorf" or "Bahnhof". We should use the official name which is used by the transport companies.
