SpatialGeometryValidity
enum SpatialGeometryValidity
  SpatialGeometryValidity is an enumeration to denote the validity of a Geometry during a test of type and dimensionality.. () Enumerator:
  SpatialGeometryValidity_None | Indicates no specific validity; used for unknown or default states.
  SpatialGeometryValidity_Valid | Geometry passes a test.
  SpatialGeometryValidity_Invalid | Geometry fails a test.
  SpatialGeometryValidity_InvalidButCanBeApproximated | Geometry fails a test, but could be approximated using allowed types.
  SpatialGeometryValidity_InvalidDueToDimensionality | Geometry fails a test due to having an disallowed dimensionality.
