Hi Toby

Let's deal with the last point first. Unsure how you could describe 
'highways_authority_ref' as 'non-authoritative'.

'ncn_ref' isn't 'non-authoritative' or similar to it's a label given to 
an assigned highway by Sustrans, many miles of which are maintained by 
local authorities.

OK, main point: 'ref' was used almost from the start of OSM when Steve 
C. mapped the first ways. As the database evolved it became clear 'ref' 
was too ambiguous & so other 'ref' tags evolved. Please remember there 
were no focus groups meetings laying out a pathway concept. OSM is a 
truly organic development. Things change, evolve. As the database 
becomes more detailed so the tags become more detailed. Contributors 
should be expecting change & willing to adapt. Being fearful of change 
is not a reason for the status-quo.

I've used 'highways_authority_ref' as it was suggested as a more 
specific tag to the alternatives. As I said in my OP I'm wiling to amend 
that, but only after I've amalgamated all the relevant tags & someone 
comes up with a better alternative. So far no one has done so.

Getting all contributors to use 'highway_authority_ref' will be 
problematic, in *exactly* the same way it is for so many other tags. 
That is *not* a reason to not improve OSM's database.

General point to all: Others here & on private email appear to think I, 
& I alone, conceived this proposal. I did not. This is clearly evident 
from reading the links in my OP. If anyone wishes to criticize the 
proposal, please have the common decency to base it on facts & evidence.
