Represents a linear polygon, which may include holes.
The shell and holes of the polygon are represented by LinearRings. In a valid polygon, holes may touch the shell or other holes at a single point. However, no sequence of touching holes may split the polygon into two pieces. The orientation of the rings in the polygon does not matter.
The shell and holes must conform to the assertions specified in the OpenGIS Simple Features Specification for SQL .
