There are many naptan:* tags that are not mentioned on the page. If you 
find any that are not consistent with what you find on the ground, 
change them. Examples are bearing, street, Atcocode, landmark, all of 
which I found often to be wrong. Various authorities include different 
levels of detail, so there may be more tags than this. All are open to 
change if you find an error.

If a stop has been verified, delete the naptan:verified=*.

I should add that I sent all of the anomalies I found to my local 
councils. having said they were interested, both ignored my data, so OSM 
in my area is still more accurate that the NaPTAN data. Local 
authorities provide the data that ends up in NaPTAN. I would not, 
therefore, support updating OSM with another NaPTAN import in my local area.
