<documentation>A SimplePolygon is a specialized polygon that has a simplified encoding of the logically equivalent GML 3.2 Surface with a single GML 3.2 PolygonPatch as its surface patch consisting of a single LinearRing as its exterior boundary and does not have any interior boundary. Thus the usage of the term 'simple' here refers to a specialized polygon with a _simplified_ encoding, which is _simply_ connected (no interior rings) and uses a _simple_ closed curve (no self-crossings) to represent its single boundary ring.</documentation>
