It would be useful for is_named_objects and check_named_objects to be able to narrow validations to only allow specific types of BaseObjects.

Describe the solution you'd like

It would be useful for is_named_objects and check_named_objects to accept a parameter of the specific type(s) of named objects (e.g., class types) that are allowed for the checks.
