Dear all

During certification we found @measure of linear coordinates outside of range defined by linearPositioningSystem/@startMeasure and @endMeasure. See invalid excerpt below. To prevent this, we suggest the following semantic constraint IS:021:

"@measure of linearCoordinate, linearCoordinateBegin and linearCoordinateEnd must be within the range defined by @startMeasure and @endMeasure of the corresponding linearPositioningSystem"

Please let us know if you do not agree with the suggested semantic constraint IS:021 till 2025-04-30. How could the wording be improved to avoid misunderstandings especially for people new to railML?

Thanks in advance!
        <linearPositioningSystem id="jjj" units="km" startMeasure="11.333" linearReferencingMethod="absolute" endMeasure="12.222">
        </linearPositioningSystem>

        <electrificationSection contactLineType="overhead" id="xxx">
          <linearLocation id="yyy">
            <associatedNetElement intrinsicCoordBegin="0" intrinsicCoordEnd="1" keepsOrientation="true" netElementRef="zzz">
              <linearCoordinateBegin measure="0" positioningSystemRef="jjj"></linearCoordinateBegin>
              <linearCoordinateEnd measure="1.4" positioningSystemRef="jjj"></linearCoordinateEnd>
            </associatedNetElement>
          </linearLocation>
        </electrificationSection>
