How would you suggest that data is tagged so that a renderer or a router 
knows the true local situation, e.g. "This reference tag, B1363, appears 
on signs is nationally unique and is something that drivers can use as a 
reference, but this other reference tag, C91, doesn't appear on signs, 
is unique only to the local authority that issued it, and can't be used 
for navigation"?  It's not as simple as saying "all B road refs and 
signed and all C road refs are unsigned" - there are quite a few exceptions.
