// Returns information about the specified workflow type. This includes configuration
// settings specified when the type was registered and other information such
// as creation date, current status, etc.
//
// 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. 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.
// For details and example IAM policies, 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.
