 Just idea dump:
 GRASS should provide ability for users to define custom vector topology
 validation rules. Rules could take into account features from single or
 multiple vector maps (layers). Probably useage of plain attribute or
 geometry and not only topology validation rules should be considered too.

 Such validation rules could be taken into account during map editing
 (digitizing) and/or used for vector map validation (v.validate).

 Examples of possible rules in human readable form:
  * Water hydrant (point) must be located on water pipe (line);
  * There should be no holes (areas without centroid) in this map;
  * Road of type X can not cross area of type Y;
  * Z areas can not share boundary with Q areas.
