public interface UtilValidationRule extends FUSRule
EnumValidationRule or RegexpValidationRule rules are not enough,
e.g there are too many possible values or they are dynamically generated.
Make sure that your UtilRuleProducer is able to create new validation rule.
Example: {util#class_name} checks that the value is a class name from platform, JB plugin or a plugin from JB plugin repository.
