-- Registers a new /workflow type/ and its configuration settings in the specified domain.
--
--
-- The retention period for the workflow history is set by the 'RegisterDomain' action.
--
-- /Important:/ If the type already exists, then a @TypeAlreadyExists@ fault is returned. You cannot change the configuration settings of a workflow type once it is registered and it must be registered as a new version.
--
-- __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.
--
--     * Constrain the following parameters by using a @Condition@ element with the appropriate keys.
--
--     * @defaultTaskList.name@ : String constraint. The key is @swf:defaultTaskList.name@ .
--
--     * @name@ : String constraint. The key is @swf:name@ .
--
--     * @version@ : String constraint. The key is @swf:version@ .
--
--
--
--
--
-- 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 <http://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/ .

-- | Creates a value of 'RegisterWorkflowType' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'rwtDefaultLambdaRole' - The default IAM role attached to this workflow type.
--
-- * 'rwtDefaultChildPolicy' - If set, specifies the default policy to use for the child workflow executions when a workflow execution of this type is terminated, by calling the 'TerminateWorkflowExecution' action explicitly or due to an expired timeout. This default can be overridden when starting a workflow execution using the 'StartWorkflowExecution' action or the @StartChildWorkflowExecution@ 'Decision' . The supported child policies are:     * @TERMINATE@ – The child executions are terminated.     * @REQUEST_CANCEL@ – A request to cancel is attempted for each child execution by recording a @WorkflowExecutionCancelRequested@ event in its history. It is up to the decider to take appropriate actions when it receives an execution history with this event.     * @ABANDON@ – No action is taken. The child executions continue to run.
--
-- * 'rwtDefaultTaskList' - If set, specifies the default task list to use for scheduling decision tasks for executions of this workflow type. This default is used only if a task list isn't provided when starting the execution through the 'StartWorkflowExecution' Action or @StartChildWorkflowExecution@ 'Decision' .
--
-- * 'rwtDefaultTaskPriority' - The default task priority to assign to the workflow type. If not assigned, then @0@ is used. Valid values are integers that range from Java's @Integer.MIN_VALUE@ (-2147483648) to @Integer.MAX_VALUE@ (2147483647). Higher numbers indicate higher priority. For more information about setting task priority, see <http://docs.aws.amazon.com/amazonswf/latest/developerguide/programming-priority.html Setting Task Priority> in the /Amazon SWF Developer Guide/ .
--
-- * 'rwtDefaultExecutionStartToCloseTimeout' - If set, specifies the default maximum duration for executions of this workflow type. You can override this default when starting an execution through the 'StartWorkflowExecution' Action or @StartChildWorkflowExecution@ 'Decision' . The duration is specified in seconds; an integer greater than or equal to 0. Unlike some of the other timeout parameters in Amazon SWF, you cannot specify a value of "NONE" for @defaultExecutionStartToCloseTimeout@ ; there is a one-year max limit on the time that a workflow execution can run. Exceeding this limit always causes the workflow execution to time out.
--
-- * 'rwtDefaultTaskStartToCloseTimeout' - If set, specifies the default maximum duration of decision tasks for this workflow type. This default can be overridden when starting a workflow execution using the 'StartWorkflowExecution' action or the @StartChildWorkflowExecution@ 'Decision' . The duration is specified in seconds, an integer greater than or equal to @0@ . You can use @NONE@ to specify unlimited duration.
--
-- * 'rwtDescription' - Textual description of the workflow type.
--
-- * 'rwtDomain' - The name of the domain in which to register the workflow type.
--
-- * 'rwtName' - The name of the workflow type. The specified string must not start or end with whitespace. It must not contain a @:@ (colon), @/@ (slash), @|@ (vertical bar), or any control characters (@\u0000-\u001f@ | @\u007f-\u009f@ ). Also, it must not contain the literal string @arn@ .
--
-- * 'rwtVersion' - The version of the workflow type. The specified string must not start or end with whitespace. It must not contain a @:@ (colon), @/@ (slash), @|@ (vertical bar), or any control characters (@\u0000-\u001f@ | @\u007f-\u009f@ ). Also, it must not contain the literal string @arn@ .
