I agree that the main reason superroute was invented was to link international routes. I agree that the documentation on the wiki might be read as implying that this is the only use. However, take a close look at what the first paragraph of https://wiki.openstreetmap.org/wiki/Super-Relation says and doesn't say: A *super-relation* is a relation <https://wiki.openstreetmap.org/wiki/Relation> that contains other relations. Relations <https://wiki.openstreetmap.org/wiki/Relations> have initially been created to contain nodes <https://wiki.openstreetmap.org/wiki/Node>, ways <https://wiki.openstreetmap.org/wiki/Way> or areas <https://wiki.openstreetmap.org/wiki/Area> and combinations thereof. Nothing there about being only for linking international routes. It doesn't even mention international routes. It says, quite explicitly that it is a relation that contains other relations. Which is what your proposal wants to do. Further down that page it does mention international routes, but as ONE example of how super-relations may be used. And then it links to other pages telling you how to implement a super-relation of routes using type=superroute. If you wanted to create a nested relation hierarchy of objects that are not routes, your proposal might have merit, because using superroute to nest relations of non-routes is counterintuitive. But you want nested routes, and that is exactly what superroute is for. If you trawl through all the discussion about superroute over the years, you'll find people arguing that it is useful and sensible (I agree). You'll also find people arguing that it is evil, should be extirpated, and that people who use it should be blocked from ever using OSM again, as should their children and their children's children, even unto the fifth generation. So if you use superroute, which does EXACTLY what you want to do, some people will be unhappy. If you invent a new tag to do EXACTLY the same thing as superroute then everyone will be unhappy, whether they think superroute is a good idea or a bad idea. Your time would be better spent documenting superroute with greater clarity. -- Paul
