Although I cannot add anything useful to the discussion about prow:ref and
prow_ref, I do have some thoughts about the content of the tag.
Often the data a council provides about a PROW includes duplication. For
example, often the parish is given as a nice friendly name and also as a
number. Here's an example of the data given about a PROW that is provided
by Devon County Council (both council and PROW chosen at random):
<SimpleData name="PARISH">Abbots Bickington</SimpleData>
<SimpleData name="NUMBER1">Abbots Bickington Footpath 1</SimpleData>
So the id of the parish appears three times (twice as a name and once
as a number); the number of the path appears three times; and the fact that
it is a footpath appears three times.
For this, I guess you've got a choice betwen using the contents of CODE or
NUMBER1. I would recommend choosing whatever appears on the Council's
interactive map. Devon County Council uses the contents of the NUMBER1
Abbots Bickington Footpath 1

My view is that it would be useful to include the id of the council as I
do not think it's obvious which authority is involved. For example, the
data for Devon does not include Torbay. And Bedfordshire is provided by
two councils: Bedford and Central Bedfordshire. Gloucestershire is
provided by the councils of Gloucestershire and South Gloucestershire.
For my web site (www.rowmaps.com), I've chosen to use the two letter codes
that are used by the OS Opendata 1:50 000 Scale Gazetteer:
The two letter code is in field 12 of their colon-separated file. There
are 208 different values. Fields 13 and 14 of that file also provide
short names and long names.
Here are some examples of fields 12, 13 and 14:
BK:C Beds:Central Bedfordshire
SG:S Glos:South Gloucestershire
Either you bundle the id of the council in with the name of the PROW as
Devon Abbots Bickington Footpath 1
Or as suggested by Craig you could provide it in a separate tag - he was
suggesting "prow:operator" or "prow:authority".
All of the data for councils that I've seen specify the parish in which
the PROW appears. So, really there are three separate pieces of
id of council
id of parish
id of PROW
