The formal parameter name is arbitrary. In the previous example, the parameter name entity is used for clarity. A nontrivial script would depend on the formal parameter entity.
If the customObjectRef attribute is present on the <ConditionScript> element, the script operates on a pair of arguments arguments called custom and input. The following script implements a function that always returns the same trivial implementation of Predicate<EntityDescriptor> regardless of the custom argument. The resulting predicate is then applied to the input argument, which always returns false.
