[Tagging] Roles of route members (was: Merging tagging scheme on wiki pages of Hiking, ...)

[Peter Elderson]

Your viewpoint is different from mine. You want to do the routing. I want
to avoid that, because the routing has already been done. The OSM-relation
IS a route. It is entered as an exact chain of ways to folllow.

OsmAnd and Garmin should take the route itself, not waypoints to route to.
It is odd that OsmAnd cannot navigate me along an ÒSM route that's shown on
the map and is readily available from OSM. Instead, I have to translate it
into a series of waypoints (gpx), then feed that to the app, and then it
recalculates the route (chain of ways) it already had.
