 >So, if you xlink:href="1" you don't know if it's Edge, Node or Face with
 identifier
 >"1".

 The important is the unique property for anchor in the list of GML tags.
 So if you use the number 1 for node is sufficient don't use it for edge.
 Instead you know what is it,

 because in a directededge in the xlink_href the anchor can be only link an
 edge. It never could be a node or other.
 Also an anchor in a directedNode is necessary a node.

 >Beside, we are not referencing faces at all, since ISO faces and GML
 faces have a >different meaning so we don't have an identifier for the GML
 faces (by all effects >being rings rather than surfaces)

 However i guess would be better to have an ID even for faces.

 Because this allow a more simple identification of a single face in a more
 complex TopoSurface (in the GML output).
 I guess the three component of TopoSurface and TopoCurve:
 Face, Edge and Node would be identificable with an ID unique.
