To me your evaluation is correct and your tagging is wrong. Any :lanes-tag specifies the values for all lanes for the basekey. If a lane value is omitted the general (i.e. non-lane) value applies. So the tagging should be: maxspeed=80 maxspeed:lanes = 60|80|80 maxspeed:lanes?wet = 60|80|50 or using default values: maxspeed=80 maxspeed:lanes = 60|| maxspeed:lanes?wet = 60||50 And finally: don't get me wrong! I really don't care a lot if it is a:b:c=x or a:b?c=x or whatever. As long as most people can live with it, use it and applications support it I'm fine with everything. I just throw my opinions in the ring, hope that many join and we find a good and accepted solution.
