These features are derived from type I (Link Between Complete Chains and Polygons) records. They are normally all consumed by the standard reader pipeline while attachingCompleteChaingeometries toPolygonfeatures to establish their polygon geometries.PolyChainLinkfeatures have a many-to-one relationship withPolygonfeatures, and a one-to-one relationship withCompleteChainfeatures.
These features have no associated geometry.
