Should we create a list of standard age-range categories?

[espinr]

Athletics Competitions have classifications based on age and gender. There is already a property named 'age range' to specify age in Text.

IAAF and WMA have concrete rules about this, but there are other federations using alternatives. For instance, NACAC used to had a U25 category, now U23. We cannot control all these exceptions.

Should we define a list of age categories with all of the standard ones? See a preliminary list. In this case, we will have a classification for those standard ones, enabling others to use their own text for exceptions like U25.
