// ChangeMessageVisibilityBatchRequest returns a request value for making API operation for
// Amazon Simple Queue Service.
//
// Changes the visibility timeout of multiple messages. This is a batch version
// of ChangeMessageVisibility. The result of the action on each message is reported
// individually in the response. You can send up to 10 ChangeMessageVisibility
// requests with each ChangeMessageVisibilityBatch action.
//
// Because the batch request can result in a combination of successful and unsuccessful
// actions, you should check for batch errors even when the call returns an
// HTTP status code of 200.
//
// Some actions take lists of parameters. These lists are specified using the
// param.n notation. Values of n are integers starting from 1. For example,
// a parameter list with two elements looks like this:
//
// &AttributeName.1=first
//
// &AttributeName.2=second
//
//    // Example sending a request using ChangeMessageVisibilityBatchRequest.
//    req := client.ChangeMessageVisibilityBatchRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
