The linestrings lying outside the neatline will not appear in the file. As specified in section 6.4.2, the neatline will be noded where it intersects the polygon. Polygon sets are used to represent tenures or regions that consist of one or more disjoint parcels or areas. Holes are represented by polygons contained entirely inside the parent polygon and which do not contain an inside point. Linework for holes should be digitized in a counter-clockwise direction.
Holes carry the same Feature Code and Feature ID as the parent.
Holes carry the same Feature Code and Feature ID as the parent polygon. A coverage of non-overlapping polygons may be either continuos or discontinuous, i.e. may completely cover the area of the map or may contain holes. Each polygon is a closed sequence of linestrings that contains an inside point. Polygon holes are implied. A closed sequence of linestrings that do not contain an inside point form a hole in the coverage.
