    form controls: validate *before* propagating value, but only on commit
    
    *Before* propagating, because after it is propagated it is too late!
    
    Only on commit (unless the control is not commitable), because
    validating each time the control value changes leads to a validator
    being called each time the user enters a character of the value.
    So each validator necessarily has to accept any prefix of a valid
    value, which often defeats the purpose. E.g. one cannot do a valiator
    that enforces a minimum length, or minimum password complexity.
    
    So validating on commit makes much more sense. That's when the user
    is trying to actually set the value as a complete value.
