Single value or multiple values?

Currently, I mostly used this were instead of one or several values, one should use a single other value ( several → 1 ). A sample is Windows one of the platform property constraint. These can easily be convert with {{Autofix}} or similar.

Supposedly we could also use this where one value is considered too general and one of several others shouuld be used ( 1 → several ). --- Jura 13:23, 16 July 2021 (UTC)
