Not only for Commons categories

This property was created originally for Commons categories (see property proposal discussion). But it can also be used for other Wikimedia projects' categories. For example, Q8607619 (Category:Maps of the United States), which includes both Wikipedia categories and a Commons category, is the value of this property for Q30 (United States of America). So I changed this property's descriptions and labels (see, e.g., this and this) accordingly. --Neo-Jay (talk) 17:20, 1 February 2020 (UTC)

@Romaine: As per this section, please consider modify the Dutch translation of this property, afaik the Dutch translation is the only one which still mentioned "Commons". --Liuxinyu970226 (talk) 03:54, 2 March 2020 (UTC)
