       This module is used directly by Config::Model::Node to dump the content of a configuration tree in perl
       data structure.

       The perl data structure is a hash of hash. Only CheckList content is stored in an array ref.

       User can pass a sub reference to apply to values of boolean type. This sub can be used to convert the
       value to an object representing a boolean like boolean. (since 2.129)

       Note that undefined values are skipped for list element. I.e. if a list element contains
       "('a',undef,'b')", the data structure then contains 'a','b'.

dump_annotations_as_pod
       Return a string formatted in pod (See perlpod) with the annotations.

       Parameters are:

       node
           Reference to a Config::Model::Node object. Mandatory

       check_list
           Yes, no or skip
