False positive test "Missing name:* translation"

[Solarspot]

What steps will reproduce the problem?

1. Load and validate ​https://www.openstreetmap.org/relation/2613797#map=19/50.96727/6.85570&layers=N
2. There is a wrong "Missing name:* translation" validation result.

What is the expected result?

name=Ehrenfeld and name:prefix=Ortsteil should not trigger a missing translation warning.

What happens instead?

The test NameMismatch considers every tag key that starts with "name:" a name localization, like "name:fr=Londres". However there are other keys that start with name: name:prefix, name:suffix, name:left, name:right, even with date-namespace: "name:1953-1990"

They all should be excluded from the test. In code, "name:etymology:wikidata" is already excluded.

A cleaner solution would be to only regard the real language codes ISO 639-1 after "name:" for the further check.

Please provide any additional information below. Attach a screenshot if possible.

We can't, we have unofficial regional language codes in the database which are not recognized by ISO. We must extend the blacklist.
