// TerminateWorkflowExecutionRequest returns a request value for making API operation for
// Amazon Simple Workflow Service.
//
// Records a WorkflowExecutionTerminated event and forces closure of the workflow
// execution identified by the given domain, runId, and workflowId. The child
// policy, registered with the workflow type or specified when starting this
// execution, is applied to any open child workflow executions of this workflow
// execution.
//
// If the identified workflow execution was in progress, it is terminated immediately.
//
// If a runId isn't specified, then the WorkflowExecutionTerminated event is
// recorded in the history of the current open workflow with the matching workflowId
// in the domain.
//
// You should consider using RequestCancelWorkflowExecution action instead because
// it allows the workflow to gracefully close while TerminateWorkflowExecution
// doesn't.
//
// 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 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.
