Mapping the fences would have to be in addition to the various pavements and 
service roads. The pavement is on one side of a service road, there is a fence 
between the service road and the main carriage way and not enough room for 
someone to walk, and then openings for pedestrian crossings, some with 
markings on the service road, with fenced staggered pedestrian areas on the 
central reservation. But perhaps 100 yards away, there will actually be a 
pavement between the service road and the carriage way and no fences. There is 
a bus bay as well, just to add to the fun :)

I've just been out to pick up some shopping and started to look at the actual 
path situations on the roads I was driving down, and it does get amazingly 
complex. The B road near by has a path down one side, separated from the road 
by a grass verge, but it stops ( probably on the county boundary ;) ) and 
becomes a sidewalk on the other side of the road into the next village. 
Through the next village, the footpath takes a complex route, only rejoining 
the side of the road towards the other end of the village. It looks like I 
need to expand the local mapping to include all of this and THEN sort out how 
it should be tagged. But adding highway=footpath down the side of 
highway=secondary just seems totally out of place ..... ? There is only one 
roadway ...
