Usage on statements with other datatypes

The English description restricts the usage of this qualifier to statements having a quantity as its value. I think it can be useful to qualify also other statements that are true relative to another object. My use case would be foil (Q5563727) where one character is a foil relative to another character (e.g. Christian Buddenbrook). It is also already used on lighthouses to say that one lighthouse is an upper light relative to another lighthouse (Nordenham range rear (Q30342271)). Does anybody see problems with this kind of usage? If not I will change the English description. - Valentina.Anitnelav (talk) 11:53, 14 December 2017 (UTC)
