AFAIK current practice is actually VERY simple. This stuff came from when we 
were experimenting with different ways to represent rights, myself included, 
and is more
complicated than necessary.

>From my understanding, a minimum of ONE to TWO tags are needed:

a) a highway tag. This represents the physical properties of the way, e.g. 
service, track, path (or footway - see below)
b) if applicable, a designation tag. This represents the RoW status.

Occasionally others are needed.

c) Addition of foot, horse, and so on to add additional rights. For instance, 
if you know a path has permissive foot rights,
add foot=permissive. Same with horse, or bicycle, so if a public footpath has 
permissive horse righs you'd have horse=permissive in addition to 
designation=public_footpath.

The one area which there is not consistency is whether to use highway=footway 
or highway=path. I prefer path, and for consistency, generally retag nearby 
footways as paths whenever I add new ways, though I've discovered in one or two 
cases I've been unknowingly participating in an edit war with the status 
alternating between path and footway :-) TBH though, I don't really care too 
much about footway vs path, and often they seem to be interchangeable, though 
many people, myself included, tend to intepret footway as urban/concrete and 
path as rural/mud.

Subject: [Talk-GB] "United Kingdom Tagging Guidelines" on the OSM wiki: due     
for an update?

Re https://wiki.openstreetmap.org/wiki/United_Kingdom_Tagging_Guidelines

Rob Nickerson mentioned that the access table currently languishing on
the talk page which got generated as a side effect of the preset file
project should be integrated into the main page. I think we need to go a
bit further and give the page a rewrite, since it's outdated and rather
unclear and variable in the advice it currently gives. I'm prepared to
give it a go; anyone want to help out? Rough plan at

https://wiki.openstreetmap.org/wiki/Talk:United_Kingdom_Tagging_Guidelines#Resolving_the_.22Classic_vs._Global_tagging_style.22_mess

I think we should drop recommendations of highway=path + access tags
completely, because nobody really seems to be using that scheme. Go with
the hybrid approach building on existing understated tagging as
outlined in the link above, but state that a) designation=* is needed to
be meaningful about rights of way, b) access tags can optionally be
added and actually do make the map data more globally useful.

Who's with me? Any against? I'd *love* to know up front if anyone has
any evidence of big areas of "highway=path + access tags" used as a
representation of actual signposted RoWs anywhere in England or Wales.
