            <para>
              The eml-spatialVector module allows for the description of
              spatial objects in a GIS system that are not defined in a
              regularly gridded pattern.  These geometries include points and
              vectors and the relationships among them.  Specific attributes of
              a spatial vector can be documented here including the vector's
              geometry type, count and topology level.
