-- __Access Control__
--
-- You can use IAM policies to control this action'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 does not 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 will be set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see <http://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html Using IAM to Manage Access to Amazon SWF Workflows> .
