Notes
-----

.. note::
   - For the type of options *data* and *criteria* refer to the individual validate plugin documentation that is represented in the value of *engine* option.
   - For additional plugin configuration options refer to the individual validate plugin documentation that is represented by the value of *engine* option.
   - The plugin configuration option can be either passed as task or environment variables.
   - The precedence of the validate plugin configurable option is task variables followed by the environment variables.
