It would be useful to add a topology rule so that points must not be covered by lines. This rule could verify that address points are not covered by a road, which should be invalid because the address point must be on one or the other side of the road.
In addition, it might be useful to also add a rule so that lines may not be inside multiple polygons. This could be useful to make sure a road that has a state name does not fall inside multiple states. *Note I am not sure if the rule "must be inside" applies to any polygon or just a single polygon.
