// Used by deciders to tell the service that the DecisionTask identified by the
// taskToken has successfully completed. The decisions argument specifies the list
// of decisions made while processing the task. A DecisionTaskCompleted event is
// added to the workflow history. The executionContext specified is attached to the
// event in the workflow execution history. Access Control If an IAM policy grants
// permission to use RespondDecisionTaskCompleted, it can express permissions for
// the list of decisions in the decisions parameter. Each of the decisions has one
// or more parameters, much like a regular API call. To allow for policies to be as
// readable as possible, you can express permissions on decisions as if they were
// actual API calls, including applying conditions to some parameters. For more
// information, see Using IAM to Manage Access to Amazon SWF Workflows
// (https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html)
// in the Amazon SWF Developer Guide.
