A Vertex_point is a topological construct corresponding to a point. It has dimensionality 0 and extent 0. The geometric location of the Vertex_point is defined by an associated point.
The data associated with a Vertex_point are the following:
vertex_geometry
The vertex_geometry specifies the geometric point that defines the position in geometric space of the vertex point.
See vertex_point to point for the application assertion.
