LocationInformationRequest for quay returns corresponding stopPlace, not quay

[GerdC]

I'd like to get coordinates of quay de:08111:6160:1:2 to draw it on a map.

I sent the following request to the TRIAS server

<?xml version="1.0" encoding="UTF-8"?>
    <Trias version="1.2" xmlns="http://www.vdv.de/trias" xmlns:siri="http://www.siri.org.uk/siri">
        <ServiceRequest>

            <RequestPayload>
                <LocationInformationRequest>
                  <LocationRef>
                     <StopPointRef>de:08111:6160:1:2</StopPointRef>
                  </LocationRef>
                </LocationInformationRequest>
            </RequestPayload>
        </ServiceRequest>
    </Trias>

The TRIAS server responds with

<?xml version="1.0" encoding="UTF-8"?>

				</trias:LocationResult>
			</trias:LocationInformationResponse>

	</trias:ServiceDelivery>
</trias:Trias>

Which is the corresponding stopPlace de:08111:6160 with the stopPlace coordinate, not the quay.

Also layers are returned as stopPlaces.

For simple bus stops or tram stations, this is often on the wrong side of the street/track, for more complex stop places with trains and busses, the coordinate is completely off.

Is this my fault, can I send a better request, or is this a bug in the MENTZ implementation of TRIAS, or is this intended by the VDV standard?
