Grop="PassengerSafetyEquipmentGroup" contains element="HeightOfSosPanel" that refers to "SosPanel", but element="SosPanel" is missing in this group. I have found "SosPhones" instead. It seems to be wrong, because NeTEx-Model contains "SosPanel" element.

Proposed solution:
- remove "SosPhones" element
- add "SosPanel" element
