I wouldn't worry about validators flagging it as an error. By the nature of things they always lag behind new tagging. JOSM flagging it as an error is only a serious problem if it refuses to let you save it. As for data consumers, maybe this would work (I haven't thought through all the ramifications). Create a route with route=hiking;bicycle. Then create two route masters, one with route_master=hiking and the other with route_master=bicycle; each route master includes the common route=hiking;bicycle. This might solve some problems. It will also likely cause different problems. The alternative, of course, is to use JOSM to clone the route, set one copy to route=hiking and the other copy to route=bicycle. But that will be a pain in the bum to maintain the route changes. -- Paul
