  <annotation>
    <documentation>A SimpleLineStringSegment is a curve segment that is defined by two or more coordinate tuples, with linear interpolation between them. Note: SimpleLineStringSegment implements GM_LineString of ISO 19107, but allows only one way of specifying the direct positions.</documentation>
