// Starts an execution of the workflow type in the specified domain using the
// provided workflowId and input data. This action returns the newly started
// workflow execution. 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.
//   - tagList.member.0 : The key is swf:tagList.member.0 .
//   - tagList.member.1 : The key is swf:tagList.member.1 .
//   - tagList.member.2 : The key is swf:tagList.member.2 .
//   - tagList.member.3 : The key is swf:tagList.member.3 .
//   - tagList.member.4 : The key is swf:tagList.member.4 .
//   - taskList : String constraint. The key is swf:taskList.name .
//   - workflowType.name : String constraint. The key is swf:workflowType.name .
//   - workflowType.version : String constraint. The key is
//     swf:workflowType.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 .

	//
	// This member is required.
	Domain *string

	// The user defined identifier associated with the workflow execution. You can use
	// this to associate a custom identifier with the workflow execution. You may
	// specify the same identifier if a workflow execution is logically a restart of a
	// previous execution. You cannot have two open workflow executions with the same

	WorkflowType *types.WorkflowType

	// If set, specifies the policy to use for the child workflow executions of this
	// workflow execution if it is terminated, by calling the
	// TerminateWorkflowExecution action explicitly or due to an expired timeout. This
	// policy overrides the default child policy specified when registering the
	// workflow type using RegisterWorkflowType . 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.
	// A child policy for this workflow execution must be specified either as a
	// default for the workflow type or through this parameter. If neither this
	// parameter is set nor a default child policy was specified at registration time
	// then a fault is returned.

	// The total duration for this workflow execution. This overrides the

	// of the other timeout parameters in Amazon SWF, you cannot specify a value of
	// "NONE" for this timeout; there is a one-year max limit on the time that a
	// workflow execution can run. An execution start-to-close timeout must be

	// is registered. If neither this parameter nor a default execution start-to-close
	// timeout is specified, a fault is returned.

	// be meaningful to the workflow you are starting. This input is made available to
	// the new workflow execution in the WorkflowExecutionStarted history event.
	Input *string

	// The IAM role to attach to this workflow execution. Executions of this workflow
	// type need IAM roles to invoke Lambda functions. If you don't attach an IAM role,
	// any attempt to schedule a Lambda task fails. This results in a
	// ScheduleLambdaFunctionFailed history event. For more information, see

	// maximum of 5 tags. You can list workflow executions with a specific tag by
	// calling ListOpenWorkflowExecutions or ListClosedWorkflowExecutions and
	// specifying a TagFilter .
	TagList []string

	// The task list to use for the decision tasks generated for this workflow
	// execution. This overrides the defaultTaskList specified when registering the
	// workflow type. A task list for this workflow execution must be specified either
	// as a default for the workflow type or through this parameter. If neither this
	// parameter is set nor a default task list was specified at registration time then

	// \u007f-\u009f ). Also, it must not be the literal string arn .
	TaskList *types.TaskList

	// The task priority to use for this workflow execution. This overrides any
	// default priority that was assigned when the workflow type was registered. If not
	// set, then the default task priority for the workflow type 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 Setting Task Priority (https://docs.aws.amazon.com/amazonswf/latest/developerguide/programming-priority.html)
	// in the Amazon SWF Developer Guide.
	TaskPriority *string

	// Specifies the maximum duration of decision tasks for this workflow execution.
	// This parameter overrides the defaultTaskStartToCloseTimout specified when
	// registering the workflow type using RegisterWorkflowType . The duration is
	// specified in seconds, an integer greater than or equal to 0 . You can use NONE
	// to specify unlimited duration. A task start-to-close timeout for this workflow
	// execution must be specified either as a default for the workflow type or through
	// this parameter. If neither this parameter is set nor a default task
	// start-to-close timeout was specified at registration time then a fault is
