Hi Jochen,I have produce a coutour gml file for a new area... but CRP doesn't seem to upload it. No complaint but nothing happens.It might be some changes in QGIS (latest v.3.40) output.Sending you a PM with a sample so you can have a look.
There was really a format change:old: <gml:coordinates>X,Y X,Y X,Y</gml:coordinates>new: <gml:posList>X Y X Y X Y</gml:posList>Comes with next release.
