land:PointType

All elements derived from PointType will either contain a coordinate text value ( "north east" or "north east elev"), a "pntRef" attribute value, or both. The "pntRef" attribute contains the value of a PointType derived element "name" attribute that exists elsewhere the instance data. If this element has a "pntRef" value, then it's coordinates will be retrieved from the referenced element. If an element contains both a coordinate value and a pntRef, the coordinate value should be used as the point location and the referenced point is either ignored or is used for point attributes such as number or desc.
