[OSM-newbies] Stiles

[Philip Striplin]

I don't know how common this is, globally, but in this area we have 
three sorts of stile on footpaths.

Type 1 is a simple "step-over" arrangements with a plank of wood 
providing a step about 50cm above the ground.

Type 2 is the same as type 1 with the addition of a trap door beside it 
to allow dogs through.

Type 3 looks more like two ladders leant together - about 150cm high, 
used to get over walls.

The different styles of stiles do have real implications for ease of use 
of the path (have you ever tried heaving 30kg of dog over a stile, or a 
bike over one of the big stiles?) and I think would be useful to show on 
the map.  Is there a standard for how to tag this sort of thing?  As far 
as I can see, there is only one way of showing a stile.

Thanks for any ideas.

Phil
