--
-- Used by workers to tell the service that the ActivityTask identified by
-- the @taskToken@ was successfully canceled. Additional @details@ can be
-- provided using the @details@ argument.
--
-- These @details@ (if provided) appear in the @ActivityTaskCanceled@ event
-- added to the workflow history.
--
-- Only use this operation if the @canceled@ flag of a
-- RecordActivityTaskHeartbeat request returns @true@ and if the activity
-- can be safely undone or abandoned.
--
-- A task is considered open from the time that it is scheduled until it is
-- closed. Therefore a task is reported as open while a worker is
-- processing it. A task is closed after it has been specified in a call to
-- RespondActivityTaskCompleted, RespondActivityTaskCanceled,
-- RespondActivityTaskFailed, or the task has
-- <https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dg-basic.html#swf-dev-timeout-types timed out>.
--
-- __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 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/.
