Thanks for the clarification.
So I would introduce a "vehicleOwner" element in the metadata block for
the Rollingstock binding in order to minimize confusion. That may be
used the following way:
<rollingstock...>
<vehicle...>
<classification>
<operator vehicleOwnerRef="" operatorClass="" startDate="" endDate=""/>
</classification>
</vehicle>
</rollingstock>
The "vehicleOperator" for the Timetable sub-schema stays unchanged.
Any comments appreciated.
Kind regards...
