Lifecycle prefixes don't prevent rendering, they prevent rendering *by renderers that don't understand them*. OsmAnd, for example, understands the "abandoned:" prefix on roads just fine. Knowing that the trail fork you've come to is an abandoned logging road rather than a hiking trail that hasn't yet had its spring cleaning is quite useful. (It might also understand "abandoned:" on other things, but I haven't yet had a reason to use it.) -- Mark _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
