That is exactly the intention for plenty of things, If the law changes, we don't need to update thousands of values. It's like tagging foot=no on a moterway... We all know you can't do that. Some stuff only makes sense when you know the implicit rules that apply to the way/object. The law states you can't walk on them. We don't need to tag this explicitly. But most motorways in Belgium have a maxspeed assigned, not sure where this idea comes from. (examples ?) Data consumers will use those rules , and often they are different between nations. Data consumers actually add value to OSM by incorporating these implicit tags in their rule set. They also are free to ignore some of them, and sometimes even have to to make sense. One of the reasons is to prevent troll-tags to take control/messing up logic , see http://wiki.openstreetmap.org/wiki/Trolltag > That or we define at-least the default and each mapper get to define the > differences from the world-wide norm. > (But this will cause newcomers to make many mistakes) There are some pages I think you are asking for.
