Hi Fernando Still think you should not change the meaning of a key but use an new/own key or even only a subkey for the other existing values considering living_street. Actually, I am in favour of deprecating living_street as it is already used for too many different cases and wrong in concept (at least for the original intention).
Comming back to highway=* we do not attribute who is maintaining the road nor if it is a called and signed as national, state and municipal roads but we use it to tell about the importance of the road within the traffic network and about the number of motor_vehicles using the road. cheers fly Am 03.11.2013 18:35, schrieb Fernando Trebien: > Hello fly, > > Thank you for your concern.
