<complexType name="LineStringType">
<annotation>
<documentation>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.</documentation>

<documentation>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.</documentation>
