Looks interesting. 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:

Have a nice day.
