//

//    a new workflow execution of the same type using the same workflow ID and
//    a unique run Id. A WorkflowExecutionContinuedAsNew event is recorded in
//    the history.
//
//    * FailWorkflowExecution – Closes the workflow execution and records a
//    WorkflowExecutionFailed event in the history.
//
//    * RecordMarker – Records a MarkerRecorded event in the history. Markers
//    can be used for adding custom information in the history for instance
//    to let deciders know that they don't need to look at the history beyond
//    the marker event.
//
//    * RequestCancelActivityTask – Attempts to cancel a previously scheduled
//    activity task. If the activity task was scheduled but has not been assigned
//    to a worker, then it is canceled. If the activity task was already assigned
//    to a worker, then the worker is informed that cancellation has been requested
//    in the response to RecordActivityTaskHeartbeat.
//
//    * RequestCancelExternalWorkflowExecution – Requests that a request be
//    made to cancel the specified external workflow execution and records a
//    RequestCancelExternalWorkflowExecutionInitiated event in the history.
//
//    * ScheduleActivityTask – Schedules an activity task.
//
//    * SignalExternalWorkflowExecution – Requests a signal to be delivered
//    to the specified external workflow execution and records a SignalExternalWorkflowExecutionInitiated
//    event in the history.
//
//    * StartChildWorkflowExecution – Requests that a child workflow execution
//    be started and records a StartChildWorkflowExecutionInitiated event in
//    the history. The child workflow execution is a separate workflow execution
//    with its own history.
//
//    * StartTimer – Starts a timer for this workflow execution and records
//    a TimerStarted event in the history. This timer fires after the specified
//    delay and record a TimerFired event.
//
// Access Control
//
// If you grant permission to use RespondDecisionTaskCompleted, you can use
// IAM policies to express permissions for the list of decisions returned by
// this action as if they were members of the API. Treating decisions as a pseudo
// API maintains a uniform conceptual model and helps keep policies readable.
// For details and example IAM policies, see Using IAM to Manage Access to Amazon
// SWF Workflows (http://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html)
// in the Amazon SWF Developer Guide.
//
// Decision Failure
//
// Decisions can fail for several reasons
//
//    * The ordering of decisions should follow a logical flow. Some decisions
//    might not make sense in the current context of the workflow execution
//    and therefore fails.
//
//    * A limit on your account was reached.
//
//    * The decision lacks sufficient permissions.
//
// One of the following events might be added to the history to indicate an
// error. The event attribute's cause parameter indicates the cause. If cause
// is set to OPERATION_NOT_PERMITTED, the decision failed because it lacked
// sufficient permissions. For details and example IAM policies, see Using IAM
// to Manage Access to Amazon SWF Workflows (http://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html)
// in the Amazon SWF Developer Guide.
//
//    * ScheduleActivityTaskFailed – A ScheduleActivityTask decision failed.
//    This could happen if the activity type specified in the decision isn't
//    registered, is in a deprecated state, or the decision isn't properly configured.
//
//    * RequestCancelActivityTaskFailed – A RequestCancelActivityTask decision
//    failed. This could happen if there is no open activity task with the specified
//    activityId.
//
//    * StartTimerFailed – A StartTimer decision failed. This could happen if
//    there is another open timer with the same timerId.
//
//    * CancelTimerFailed – A CancelTimer decision failed. This could happen
//    if there is no open timer with the specified timerId.
//
//    * StartChildWorkflowExecutionFailed – A StartChildWorkflowExecution decision
//    failed. This could happen if the workflow type specified isn't registered,
//    is deprecated, or the decision isn't properly configured.
//
//    * SignalExternalWorkflowExecutionFailed – A SignalExternalWorkflowExecution
//    decision failed. This could happen if the workflowID specified in the
//    decision was incorrect.
//
//    * RequestCancelExternalWorkflowExecutionFailed – A RequestCancelExternalWorkflowExecution
//    decision failed. This could happen if the workflowID specified in the
//    decision was incorrect.
//
//    * CancelWorkflowExecutionFailed – A CancelWorkflowExecution decision failed.
//    This could happen if there is an unhandled decision task pending in the
//    workflow execution.
//
//    * CompleteWorkflowExecutionFailed – A CompleteWorkflowExecution decision
//    failed. This could happen if there is an unhandled decision task pending
//    in the workflow execution.
//
//    * ContinueAsNewWorkflowExecutionFailed – A ContinueAsNewWorkflowExecution
//    decision failed. This could happen if there is an unhandled decision task
//    pending in the workflow execution or the ContinueAsNewWorkflowExecution
//    decision was not configured correctly.
//
//    * FailWorkflowExecutionFailed – A FailWorkflowExecution decision failed.
//    This could happen if there is an unhandled decision task pending in the
//    workflow execution.
//
// The preceding error events might occur due to an error in the decider logic,
// which might put the workflow execution in an unstable state The cause field
// in the event structure for the error event indicates the cause of the error.
//
// A workflow execution may be closed by the decider by returning one of the
// following decisions when completing a decision task: CompleteWorkflowExecution,
// FailWorkflowExecution, CancelWorkflowExecution and ContinueAsNewWorkflowExecution.
// An UnhandledDecision fault is returned if a workflow closing decision is
// specified and a signal or activity event had been added to the history while
// the decision task was being performed by the decider. Unlike the above situations
// which are logic issues, this fault is always possible because of race conditions
// in a distributed system. The right action here is to call RespondDecisionTaskCompleted
// without any decisions. This would result in another decision task with these
// new events included in the history. The decider should handle the new events
// and may decide to close the workflow execution.
