 *          &lt;documentation&gt;A LineString is a special curve that consists of a single segment with linear interpolation. It is defined by two or more coordinate
 *                          tuples, with linear interpolation between them. It is backwards compatible with the LineString of GML 2, GM_LineString of ISO 19107 is
 *                          implemented by LineStringSegment.&lt;/documentation&gt;
 *      &lt;/annotation&gt;
 *      &lt;complexContent&gt;
 *          &lt;extension base="gml:AbstractCurveType"&gt;
 *              &lt;sequence&gt;

 *                      &lt;annotation&gt;
 *                          &lt;documentation&gt;GML supports two different ways to specify the control points of a line string. 1. A sequence of "pos"
 *                                                          (DirectPositionType) or "pointProperty" (PointPropertyType) elements. "pos" elements are control points that are only part
 *                                                          of this curve, "pointProperty" elements contain a point that may be referenced from other geometry elements or reference
 *                                                          another point defined outside of this curve (reuse of existing points). 2. The "posList" element allows for a compact way to
 *                                                          specifiy the coordinates of the control points, if all control points are in the same coordinate reference systems and belong
 *                                                          to this curve only. The number of direct positions in the list must be at least two.&lt;/documentation&gt;
 *                      &lt;/annotation&gt;
 *                      &lt;choice maxOccurs="unbounded" minOccurs="2"&gt;
