// StartChangeSetRequest returns a request value for making API operation for
// AWS Marketplace Catalog Service.
//
// This operation allows you to request changes for your entities. Within a
// single ChangeSet, you cannot start the same change type against the same
// entity multiple times. Additionally, when a ChangeSet is running, all the
// entities targeted by the different changes are locked until the ChangeSet
// has completed (either succeeded, cancelled, or failed). If you try to start
// a ChangeSet containing a change against an entity that is already locked,
// you will receive a ResourceInUseException.
//
// For example, you cannot start the ChangeSet described in the example (https://docs.aws.amazon.com/marketplace-catalog/latest/api-reference/API_StartChangeSet.html#API_StartChangeSet_Examples)
// below because it contains two changes to execute the same change type (AddRevisions)
// against the same entity (entity-id@1).
//
//    // Example sending a request using StartChangeSetRequest.
//    req := client.StartChangeSetRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
