Concerning the unnamed "route" osm.org/relation/5742132 : is that only a mistake and is in fact part of a bigger route or does it have some real sense? Then an explanation in a "note=" or "description=" tag would be fine, if it made sense as an unamed route (or completion of name etc.), or the relation could be deleted?

It was a marked hiking trail when I was there 6 years ago, it's not a mistake.
It could be a short standalone cross-connecting trail or be part of a longer route, this was not evident from the survey. Unfortunately, I don't remember all the details after such a long time.

Yes, but the whole route relation consists only of one segment of 661 m, and is part of the Alta via n. 1 delle Dolomiti. - Which has another trail blazing.
Seems that it could be part of another local route. I changed the fixme to "incomplete" to put the attention to the route.
It was just by chance that I've seen it during an overpass query.
Thanks for your reply.
