gml:TopoVolume

gml:TopoVolume represents a homogeneous topological expression, a set of directed topologic solids, which if realised are isomorphic to a geometric solid primitive. The intended use of gml:TopoVolume is to appear within a solid feature to express the structural and geometric relationships of this solid feature to other features via the shared solid definitions.
