The idea was to treat complex bridges like this one in Istanbul, in a way that makes sense:
http://www.openstreetmap.org/relation/151818 This bridge carries two tram tracks, two lanes of vehicular traffic, and multiple footways on both sides and on two levels. The lower level also has shops and restaurants. If you look closely at it, you can see both the tram lines and the highways still use layer and bridge tags. Perhaps because the bridge relation concept is not yet in general use.
