In my opinion, yes, where provided. However, since my view is essentially London-only, (where NaptanCodes don't exist at all), I find that the Stop indicator is the most useful thing, since it is almost essential to differentiate stops at transport hubs. I don't see any problem with having a non-unique ref=, since it's be likely to be unique on a local scale which is when it is most useful. >>> Note that my OSM data entry is missing the stuff at the top of the sign >>> which Brian has been putting under the name tag I believe.
