By configuring <chainageLocationAttributeId> all locations that have a value for this attribute will be contained in this location set. This attribute will automatically be used as sortingLocationAttributeId so the locations are in the order of ascending chainage value. The attribute must be of type numeric.

Referring to the chainage location set can only be done in combination with <readWriteMode>read only</readWriteMode> by configuring <chainageLocationSetId> in <timeSeriesSet>: 

<timeSeriesSet>
        <moduleInstanceId>ExportRunMultipleTimeSeries</moduleInstanceId>
        <valueType>scalar</valueType>
        <parameterId>H.m</parameterId>
        <chainageLocationSetId>CHAINAGE_D</chainageLocationSetId>
        <timeSeriesType>external historical</timeSeriesType>
        <timeStep unit="day"/>
        <relativeViewPeriod unit="day" start="-7" end="0"/>
        <readWriteMode>read only</readWriteMode>
</timeSeriesSet>

	<locationSet id="CHAINAGE_C">
		<chainageLocationAttributeId>CHAINAGE_C</chainageLocationAttributeId>
	</locationSet>
