I think I would mimic what we do with Min/Max i.e. have AgeMin/AgeMax and an inclusive option. What I'm not sure about is if we should limit that to years. Or be more flexible and also support months/days for instance. But I'm not sure it's going to be easy (or useful?). Might be worth a try though. I would recommend doing an experiment with one date type before writing all the validators as it's going to be a bit tedious. I suppose you have seen Marko's post about how to contribute a constraint: http://in.relation.to/2018/01/04/adding-new-constraint-to-engine/ ?
