At the very least you will have to insert a non-routing node at
the boundary if there is not one there already, so that the
city change can be recorded at it.

There seems to be some room for saving space as most elements
will not use all of those.
There could be a separate address structure perhaps consisting
of (city, region, country) which could even be shared.

But anyway it only roads that can have multiple city,region,country
combinations so it could probably be added to the RoadDef in
the same way as the Numbers are (and maybe even combined with them).
