Now you're just thinking of a single renderer and its way of processing 
the data. Did you take osmarender into account? How does it handle the 
road relation at this point?

As much as people always say to not tag for the renderer, we should also 
not design tagging specifically geared towards one specific renderer.

Don't forget it's not that often that a road would cross a boundary and 
continue a long distance. Names change, refs change, maxspeed, surface, 
etc. We're already breaking it up for any number of reasons, at a border.

But, a bit of preprocessing could also be involved, so that we don't do 
'tagging for the renderer', if that makes people feel better. :P
