simple or compound geographic object to be referenced by a location reference

NOTE 1 to entry: A location is matched to database objects by location definitions, which specify what is meant by a particular location. Without any explicit remark, it is meant to be a linear stretch in terms of topology in the database network without any loops or discontinuities in between (linear location). It might also be only a point in the network as a specialization of a linear stretch with length zero. In addition to that, a location can also be a set of road elements representing an area. This area is expressible by a polygon or a list of linear locations.
