Any of the ones around Edinburgh that I have seen don't have a letter

This page doesn't cover when there is two routes along the same way.

I know there is a key for ncn route on
What is this for?

On <http://wiki.openstreetmap.org/index.php/Map_Features#References>  
it has a N in the example. Maybe we should expand this to explicitly  
state the national and regional names that should be used.
(eg N54)
to become
(eg "N54" for National Route; "R43" for regional routes)

The Map Features page above uses just "N". Personally I prefer the

The above information still doesn't clarify this problem. There  
should probably be no duplicate tags. How about using a ";" to  
separate the route numbers? What problems would that cause?
