It simply means that if one of two non-identical boolean expressions implies the other (which is an established and well-defined concept), then it is more specific. Implementing this should just be a bit of routine programming work. > The variants with keys like <key>:condition:<ordering> would solve this IMO. You could replace "specificness" with "whatever condition comes first". But that would burden the mapper with making sure that maxspeed:hgv:wet is listed before maxspeed:hgv, with no good reason why that should be important.
