Component:  topology  |     Version:  trunk

 The function should produce <gml:TopoPoint>, <gml:TopoCurve> and
 <gml:TopoSurface> for a given TopoGeometry.

 There should be a way for the function to decide about whether to write
 primitive elements "inline" or to reference them trough xlinks.
 Such a decision could be driven by an optional second argument being the
 name of a "visited" table to use for bookkeeping.

 A companion for this function would be a triplet of
 AsGML(<primitive_topology_record>) functions to write the actual
 <gml:Node>, <gml:Edge> and <gml:Face> tags, each of which should likely
 also make use of a passed-or-created "visited" table (gml:Face references
 gml:Edge, gml:Edge references gml:Node)
