+Exemption from strict API response validation
+=============================================
+
+Vendors of commercial NFVI products may have extended the Nova API to support
+proprietary add-on features. These additions can cause Nova Tempest API tests
+to fail due to unexpected data in API responses. In order to resolve this
+transparently in the context of OVP, a temporary exemption process has been
+created. More information on the exemption can be found in section
+:ref:`dovetail-exemption_process_api_response_validation`.

+Dovetail allows the user to disable strict API response validation implemented
+by Nova Tempest tests by means of the ``--no-api-validation`` option. Usage of
+this option is only advisable if the SUT returns Nova API responses that
+contain additional attributes. For more information on this command line option
+and its intended usage, refer to

 Each time the 'dovetail run' command is executed, the results in the aforementioned directory
