Natpan imports were imported at the request of local mappers, in the 
hope that they would be verified - many have not been. The Naptan tags 
do convey information about the stop that needs checking and sometimes 
correcting. I checked a lot of stops and forwarded the results of my 
checking to the local council (councils feed the data into the Naptan 
database). At first they seemed interested but as the financial belt 
tightened they seem less so.

The stop has no highway=bus_stop tag because it is a customary stop 
(naptan:BusStopType = CUS). If you do survey any of these and you find a 
bus stop sign, add a highway=bus_stop too. If you check the details on a 
survey you can then remove the naptan:verified = no tag. Check the 
street names - they can be useful indicators about road names especially 
in rural roads. The naptan:Bearing = W on that tag looks dodgy, because 
buses leaving tha stop would be heading north east (ish). I don't think 
that CUS tag is right in that case either because the naptan:Indicator = 
opp means there is a sign on the opposite side of the road so it is not 
really a customary stop, but that could be a Suffolk convention - every 
county uses the rules in their own way.
