I think it's the same information, because A1, SS3 or whatever are 
routes, containing ways and a way could contain many routes. Maybe there 
is a main-route, which you could tag in ref=*, but which route should it 
be? In some countries several routes are on the signs (international and 
national route).

It's the same "problem" as we have with cycle-routes. Typical they are 
only exist as a route-relation.
