The thing I think might be missing is that I differentiate stops that 
have a note=*.  These are the stops that I have checked, have all the 
NaPTAN tags you would expect, but one or more is in error, such as the 
bearing.  I don't change the NaPTAN tag (as discussed some time earlier) 
but add a note= tag with the thing(s) I find wrong, including if I moved 
the stop because I was sure it was in the wrong place.  If you check my 
overlay these are the cyan coloured stops.  Click on one and you will 
see the note.  My overlay is a lashup so I would really like to see 
NOVAM  working well.

That could be a problem for councils' transport teams who probably 
mostly use IE.
