[Talk-GB] tag prow_ref

[David Groom]

The prow:ref tag emerged from a discussion I started on this list about 
the problem of using the ref tag to refer to PROW references.  The 
specific problem was that some highways were also designated footpaths / 
bridleways, and so if the ref tag was used to tag a rights of way 
reference it was given the same rendering priority on these ways as a 
road reference.  There was also no way to distinguish between a ref tag 
which was for a road reference, and a ref tag which was for a prow 
reference on that road.  Thus the prow:ref tag was suggested.

At a later stage I noted the prow_ref tag started to be used.  I did not 
follow the discussion / reasoning behind that, but I find it hard to 
believe that we need both a prow_ref  tag and a prow:ref tag.  So I 
assume the prow_ref tag supoerceeded the prow:ref tag, but for the 
reasoning outlined in the first paragraph I would not think it helpful 
to simple use the plain "ref" tag on the Isle of Wight.

I cant follow the logic of  "Visibly signed things go into 'ref'", since 
that would seem to mean we don't need lcn_ref tags as these are visible 
signed.
