        # ==== Parameters
        # * domain_name<~String> - Name of domain. Must be between 3 and 255 of the
        #   following characters: a-z, A-Z, 0-9, '_', '-' and '.'.
        # * item_name<~String> - Name of the item.  May use any UTF-8 characters valid

        # * options<~Hash>:
        #   * AttributeName<~Array> - Attributes to return from the item.  Defaults to
        #     {}, which will return all attributes. Attribute names and values may use

        #     allowed in xml are not valid.  Each name and value can be up to 1024
        #     bytes long.
        #    * ConsistentRead<~Boolean> - When set to true, ensures most recent data is returned. Defaults to false.

        # * response<~Excon::Response>:
        #   * body<~Hash>:
        #     * 'Attributes' - list of attribute name/values for the item
        #     * 'BoxUsage'
