This is used by by the tuple Structuring to indicate whether the intersections of geometric objects, such as lines, are explicitly indicated by other geometric objects, such as points. The first value implies that the objects defining the intersections are included within each of the intersecting objects, but not necessarily at the ends of the object. The second value implies that all such intersections form the beginning or end of the objects. The third value connotes that there is no explicit relationship between intersecting objects.
