JOSM-Validator warns about unknown relation type 'superroute'

[anonymous]

Steps to reproduce:

1. In the Preferences enable the relation checker.
2. Create a new relation of type 'superroute'.
3. Check the modification either in the checker pane or by attempting to upload the changes.

Expected result:
JOSM doesn't warn.

Actual result:
Though JOSMs word completion previously suggested to enter type=superroute, it now warns about an unknown relation type.

The error occurs in version 8969.

This relation type is only used 265 times and there's no English page on the wiki.

I think JOSM suggest type=superroute because it is already used in an other relation in the data you have downloaded or you have added an external preset which contains this tag value.

If you work on an empty layer, only keys and values from presets are suggested. In the actual version (JOSM 8993) type=superroute is not suggested.

So the validator warning is correct.

But type=superroute is a special case. The wiki (​https://wiki.openstreetmap.org/wiki/Types_of_relation) lists superroute as an “Established Relation“, but, as Don-vip mentioned, there is no wiki page (​https://wiki.openstreetmap.org/wiki/Relation:superroute) for this value.

In OSM there is no real authority which introduce new tags or values. A common way is a discussion on the tagging mailinglist ​https://lists.openstreetmap.org/listinfo/tagging. Then there should be a wiki page, the tag or value should be "Approved" or at least widly used and at least JOSM needs a presets.

But you can create your own preset (wiki:TaggingPresets) or just ignore the warning ;)
