The definition says polygons can have any number of rings, either exterior or interior. Exterior rings are oriented clockwise, while holes are oriented counter-clockwise. Maybe the OGR driver should be improved to check for this. If more than one exterior ring is found then an OGC multi-polygon geometry object should be returned. Could check the orientation via area or the http://en.wikipedia.org/wiki/Even%E2%80%93odd_rule This message contains information, which may be in confidence and may be subject to legal privilege.
