In the UK, you'd use the same principle both outside and in, surely?  
How the roads are classified is up to the highway authority.

FWIW, in central London, all "primary A" (i.e. OSM trunk) roads  
terminate at a loop formed by the Euston Road, Edgware Road, Park  
Lane etc. etc. (the old Congestion Charge boundary, I think). So  
anything within that will be "non-primary A" (OSM primary), B (OSM  
secondary) or unclassified.
