>          Issue Type: New Feature
>    Affects Versions: 2.0.0-M5

> We can of course validate using validateNXxx(), but the idea here is to toggle off or on the optionality constraint for N>0 parameters based on earlier parameters,
> eg:
> {code:java}
> public void act(SomeType type, String someParam) {
> }
> public boolean optional1Act(SomeType type) {
>     if (type == SomeType.FOO || type == SomeType.BAR) return true;
>     return false;
> } {code}
