required will have to be non-true. I don't know if there's an el
expression that will work in your case, so you might just have to
leave it false.
The following validator works against multiple components.

You can either use it as a template for creating your own validator,
or you might be able to use the comparator attribute on it to
accomplish what you need. (Force it to compare against a constant
value of true or false instead of the inputText value). Still not
sure how that'd interact with <f:validateLongRange>
You might also be able to use pieces of the OptionalValidationFramework.
