 18.2 The OpenGIS Geometry Model
 ===============================
 
 The set of geometry types proposed by OGC's *SQL with Geometry Types*
 environment is based on the *OpenGIS Geometry Model*. In this model,
 each geometric object has the following general properties:
 
    * It is associated with a Spatial Reference System, which describes
      the coordinate space in which the object is defined.
 
    * It belongs to some geometry class.
