Set of consecutive straight segments (no branches) defined by successive vertices. Can be specialized to e.g. prisms, for instance to define 3D "areas".<br/>A linestring is expected to have the same number of vertices in all positioning systems, but the model does not enforce this. This flexibility can be useful when the linestring approximates a circle for instance.<br/>

Details:
Polyline coordinates are expressed in <u>one </u>Positioning System. Define more polylines if more positioning systems become relevant. May be left empty if polyline coordinates convey sufficient information about the positioning system.<br/>
