Documentation	The end Node of each directedEdge of a TopoCurveType is the start Node of the next directedEdge of the TopoCurveType in document order. The TopoCurve type and element represent a homogeneous topological expression, a list of directed edges, which if realised are isomorphic to a geometric curve primitive. The intended use of TopoCurve is to appear within a line feature instance to express the structural and geometric relationships of this line to other features via the shared edge definitions.
