* _lanePositionBased_ of type **SEQUENCE** (SIZE(1..4)) OF LanePositionOptions<br>
a set of up to `4` lanes that are partially or fully occupied by an object or event, ordered by increasing value of [**LanePosition**](#LanePosition).
Lanes that are partially occupied can be described using the component lanePositionWithLateralDetails of [**Options**](#Options), with the following constraints:
The distance to lane borders which are covered by the object / event shall be set to 0. Only the distances to the leftmost and/or rightmost border which are not covered by
the object / event shall be provided with values > 0. Those values shall be added to the respective instances of [**LanePositionOptions**](#LanePositionOptions), i.e. the first entry shall contain the component distanceToLeftBorder > 0 ,
and/or the last entry shall contain the component distanceToRightBorder > 0; the respective other components of these entries shall be set to 0.
* _mapBased_ of type **SEQUENCE** (SIZE(1..4)) OF MapPosition OPTIONAL<br>

If present, it shall describe the same lane(s) as listed in the component lanePositionBased, but using the lane identification of the MAPEM. This component can be used only if a
MAPEM is available for the reference position (e.g. on an intersection): In this case it is used as a synonym to the mandatory component lanePositionBased.
