Dear all

During the presentation of the forum post at the railML SCTP working group meeting from 2025-03-28 it became clear that the wording of the above suggested semantic constraints is hard to understand.

Basically, the suggested semantic constraints mean that the netElement shall be positioned using coordinates of the same kind as the positioning system referenced from associatedPositioningSystem of this netElement.

Additionally, railML.org provides the valid and invalid examples (against suggested constraint) for linearCoordinate [1].

The examples refer to the positioning approach, which can be found by the link [2].

Interpretation for geometricCorrdinate is analogous.
