Notes
-----

.. note::
   - This module requires the netconf system service be enabled on the remote device being managed.
   - This module supports devices with and without the candidate and confirmed-commit capabilities. It will always use the safer feature.
   - This module supports the use of connection=netconf
   - This module is supported on ``ansible_network_os`` network platforms. See the :ref:`Network Platform Options <platform_options>` for details.
