      :param set value:
          The set to be certified.
      :param func certifier:
          A function to be called on each value in the list to check that it is valid.
      :param int min_len:
          The minimum acceptable length for the list. If None, the minimum length is not checked.
      :param int max_len:
          The maximum acceptable length for the list. If None, the maximum length is not checked.
      :param bool include_collections:
          Include types from collections.
      :param bool required:
          Whether the value can be `None`. Defaults to True.
      :return:
          The certified set.
