// SendMessageBatchRequest returns a request value for making API operation for
// Amazon Simple Queue Service.
//
// Delivers up to ten messages to the specified queue. This is a batch version
// of SendMessage. For a FIFO queue, multiple messages within a single batch
// are enqueued in the order they are sent.
//
// The result of sending each message is reported individually in the response.
// 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.
//
// The maximum allowed individual message size and the maximum total payload
// size (the sum of the individual lengths of all of the batched messages) are
// both 256 KB (262,144 bytes).
//
// A message can include only XML, JSON, and unformatted text. The following
// Unicode characters are allowed:
//
// #x9 | #xA | #xD | #x20 to #xD7FF | #xE000 to #xFFFD | #x10000 to #x10FFFF
//
// Any characters not included in this list will be rejected. For more information,
// see the W3C specification for characters (http://www.w3.org/TR/REC-xml/#charsets).
//
// If you don't specify the DelaySeconds parameter for an entry, Amazon SQS
// uses the default value for the queue.
//
// 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 SendMessageBatchRequest.
//    req := client.SendMessageBatchRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
