// This operation 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 operation provides a suitable alternative to sending individual delete
// requests, reducing per-request overhead. The request can contain 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 operation 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.
//   - Directory buckets - S3 Versioning isn't enabled and supported for directory
//     buckets.
//   - Directory buckets - For directory buckets, you must make requests for this
//     API operation to the Zonal endpoint. These endpoints support
//     virtual-hosted-style requests in the format
//     https://bucket_name.s3express-az_id.region.amazonaws.com/key-name .
//     Path-style requests are not supported. For more information, see Regional and
//     Zonal endpoints (https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-express-Regions-and-Zones.html)
//     in the Amazon S3 User Guide.
//
// The operation supports two modes for the response: verbose and quiet. By
// default, the operation 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 operation encountered an error. For a
// successful deletion in a quiet mode, the operation 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)
// in the Amazon S3 User Guide. Directory buckets - MFA delete is not supported by
// directory buckets. Permissions
//   - General purpose bucket permissions - The following permissions are required
//     in your policies when your DeleteObjects request includes specific headers.
//   - s3:DeleteObject - To delete an object from a bucket, you must always specify
//     the s3:DeleteObject permission.
//   - s3:DeleteObjectVersion - To delete a specific version of an object from a
//     versiong-enabled bucket, you must specify the s3:DeleteObjectVersion
//     permission.
//   - Directory bucket permissions - To grant access to this API operation on a
//     directory bucket, we recommend that you use the CreateSession (https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession.html)
//     API operation for session-based authorization. Specifically, you grant the
//     s3express:CreateSession permission to the directory bucket in a bucket policy
//     or an IAM identity-based policy. Then, you make the CreateSession API call on
//     the bucket to obtain a session token. With the session token in your request
//     header, you can make API requests to this operation. After the session token
//     expires, you make another CreateSession API call to generate a new session
//     token for use. Amazon Web Services CLI or SDKs create session and refresh the
//     session token automatically to avoid service interruptions when a session
//     expires. For more information about authorization, see CreateSession (https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession.html)
//     .
//
// Content-MD5 request header
//   - General purpose bucket - The Content-MD5 request 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.
//   - Directory bucket - The Content-MD5 request header or a additional checksum
//     request header (including x-amz-checksum-crc32 , x-amz-checksum-crc32c ,
//     x-amz-checksum-sha1 , or x-amz-checksum-sha256 ) is required for all
//     Multi-Object Delete requests.
//
// HTTP Host header syntax Directory buckets - The HTTP Host header syntax is
// Bucket_name.s3express-az_id.region.amazonaws.com . 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)
