Also, this is much harder because of implicit tagging in two ways: access tags have defaults depending on other tags. highway=path has a default of yes for foot/bicycle/horse and no for car. access=no I think implies not only car=no but also foot=no. So, I would be inclined to try to set the unset tags based on types. Basically (I am bad at style rules; hopefully this makes senes): highway=path & !foot= {add foot=yes} access=$1 & ~foot= {add foot=$1} so that then a non-set access tag can be no, and railway=abandoned will default to all access being no unless tagged. I realize the above is half baked but I hope it is helpful anyway....
