    # Since 4x does not support dynamic scoping, all names are absolute and can be
    # used as is (with some check/transformation/mangling between absolute/relative form
    # due to Puppet::Resource's idiosyncratic behavior where some references must be
    # absolute and others cannot be.
    # Thus there is no need to call scope.resolve_type_and_titles to do dynamic lookup.
