two_sided

I question the definition of two_sided. Obviously every wall has 2 sides, but I don't agree you can call these equivalent, just because they have the same height on the inside and on the outside. Usually the inside of a city wall is quite different from the outside, it is constructed in a way that the defenders can move quickly and defend (i.e. there will usually be rooms and corridors on the inside, while the outside will be very closed). So even if the height is equal, there will still be no equality between these two sides.--Dieterdreist (talk) 09:59, 16 May 2013 (UTC)

I recommend shifting from low/high as a distinction to inside/outside. If the right side is considered the "outside" then nothing will need to be changed for existing "one sided" walls. I'm mapping the historic stockade walls of Albany NY in OpenHistoricalMap and the city_wall barrier in its current form is a little bit off from what is needed, but simple changes make it work. One is the inside/outside tweak; another would be something like city_wall=palisade to denote wood log construction per the description of a palisade in Wikipedia.
