     16The actual _definition_ of each !TopoGeometry is contained in the [wiki:TopologyTableRelation relation] table of the topology identified by "topology_id". The "relation" table contains a record for each component of each TopoGeometry. Interpretation of the component also requires looking at the [wiki:TopologyTableLayer topology.layer] table, which tells if element_type refers to primitive type (node, edge, face) or another layer (in case of hierarchical !TopoGeometry).
