This attribute represents a waypoint in a relation. It extends
Location, meaning that can be associated with a physical location
in a visual rendition. It can optionally be associated with another
instance of Vertex to indicate that there is a path from this
one to the other one. Cyclic paths are not permitted, although
currently that is not enforced by this class.
