-- | Provides the details of the @CancelWorkflowExecution@ decision.
--
-- __Access Control__
--
-- You can use IAM policies to control this decision\'s access to Amazon
-- SWF resources as follows:
--
-- -   Use a @Resource@ element with the domain name to limit the action to
--     only specified domains.
--
-- -   Use an @Action@ element to allow or deny permission to call this
--     action.
--
-- -   You cannot use an IAM policy to constrain this action\'s parameters.
--
-- If the caller doesn\'t have sufficient permissions to invoke the action,
-- or the parameter values fall outside the specified constraints, the
-- action fails. The associated event attribute\'s @cause@ parameter is set
-- to @OPERATION_NOT_PERMITTED@. For details and example IAM policies, see
-- <https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html Using IAM to Manage Access to Amazon SWF Workflows>
-- in the /Amazon SWF Developer Guide/.
