// This action enables you to delete multiple objects from a bucket using a single
// HTTP request. If you know the object keys that you want to delete, then this
// action provides a suitable alternative to sending individual delete requests,
// reducing per-request overhead. The request contains a list of up to 1000 keys
// that you want to delete. In the XML, you provide the object key names, and
// optionally, version IDs if you want to delete a specific version of the object
// from a versioning-enabled bucket. For each key, Amazon S3 performs a delete
// action and returns the result of that delete, success, or failure, in the
// response. Note that if the object specified in the request is not found, Amazon
// S3 returns the result as deleted. The action supports two modes for the
// response: verbose and quiet. By default, the action uses verbose mode in which
// the response includes the result of deletion of each key in your request. In
// quiet mode the response includes only keys where the delete action encountered
// an error. For a successful deletion, the action does not return any information
// about the delete in the response body. When performing this action on an MFA
// Delete enabled bucket, that attempts to delete any versioned objects, you must
// include an MFA token. If you do not provide one, the entire request will fail,
// even if there are non-versioned objects you are trying to delete. If you provide
// an invalid token, whether there are versioned keys in the request or not, the
// entire Multi-Object Delete request will fail. For information about MFA Delete,
// see MFA Delete (https://docs.aws.amazon.com/AmazonS3/latest/dev/Versioning.html#MultiFactorAuthenticationDelete)
// . Finally, the Content-MD5 header is required for all Multi-Object Delete
// requests. Amazon S3 uses the header value to ensure that your request body has
// not been altered in transit. The following operations are related to
// DeleteObjects :
// - CreateMultipartUpload (https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateMultipartUpload.html)
// - UploadPart (https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPart.html)
// - CompleteMultipartUpload (https://docs.aws.amazon.com/AmazonS3/latest/API/API_CompleteMultipartUpload.html)
// - ListParts (https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListParts.html)
// - AbortMultipartUpload (https://docs.aws.amazon.com/AmazonS3/latest/API/API_AbortMultipartUpload.html)
