How come you don't think content sescriptor should be a required qualifier? @Máté:--Trade (talk) 12:30, 25 July 2020 (UTC)

@Trade: Because in a very large number of cases there are no descriptors. I.e. it is not required. – Máté (talk) 12:57, 25 July 2020 (UTC)

This would be a good time to use suggestion constraint. --Trade (talk) 08:00, 7 September 2020 (UTC)

I am not that sure but I don't mind. Máté (talk) 09:30, 7 September 2020 (UTC)
