Yeah. Truly. I completely missed that :-)

Makes sense now. And that does indeed look easily parseable. When I have a moment later today I'll check if this can successfully imported with Subsurface (and if it is easier to change our parser or if it requires changes to the XML to be easily digestable).
Ideally this would then match the dives (more loosely than normal since you will have taken the GPS fix a few minutes before dive start or a few minutes after dive end) and then simply updates the dive…

If you or Lubumir have time to play with that right now, please say so here (so we don't duplicate work) and go ahead!
