// Removes an object from a bucket. The behavior depends on the bucket's
// versioning state:
//
//   - If bucket versioning is not enabled, the operation permanently deletes the
//     object.
//
//   - If bucket versioning is enabled, the operation inserts a delete marker,
//     which becomes the current version of the object. To permanently delete an object
//     in a versioned bucket, you must include the object’s versionId in the request.
//     For more information about versioning-enabled buckets, see [Deleting object versions from a versioning-enabled bucket].
//
//   - If bucket versioning is suspended, the operation removes the object that
//     has a null versionId , if there is one, and inserts a delete marker that
//     becomes the current version of the object. If there isn't an object with a null
//     versionId , and all versions of the object have a versionId , Amazon S3 does
//     not remove the object and only inserts a delete marker. To permanently delete an
//     object that has a versionId , you must include the object’s versionId in the
//     request. For more information about versioning-suspended buckets, see [Deleting objects from versioning-suspended buckets].
//
//   - Directory buckets - S3 Versioning isn't enabled and supported for directory
//     buckets. For this API operation, only the null value of the version ID is
//     supported by directory buckets. You can only specify null to the versionId
//     query parameter in the request.
//
//   - 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://amzn-s3-demo-bucket.s3express-zone-id.region-code.amazonaws.com/key-name
//     . Path-style requests are not supported. For more information about endpoints
//     in Availability Zones, see [Regional and Zonal endpoints for directory buckets in Availability Zones]in the Amazon S3 User Guide. For more information
//     about endpoints in Local Zones, see [Concepts for directory buckets in Local Zones]in the Amazon S3 User Guide.
//
// To remove a specific version, you must use the versionId query parameter. Using
// this query parameter permanently deletes the version. If the object deleted is a
// delete marker, Amazon S3 sets the response header x-amz-delete-marker to true.
//
// If the object you want to delete is in a bucket where the bucket versioning
// configuration is MFA Delete enabled, you must include the x-amz-mfa request
// header in the DELETE versionId request. Requests that include x-amz-mfa must
// use HTTPS. For more information about MFA Delete, see [Using MFA Delete]in the Amazon S3 User
// Guide. To see sample requests that use versioning, see [Sample Request].
//
// Directory buckets - MFA delete is not supported by directory buckets.
//
// You can delete objects by explicitly calling DELETE Object or calling ([PutBucketLifecycle] ) to
// enable Amazon S3 to remove them for you. If you want to block users or accounts
// from removing or deleting objects from your bucket, you must deny them the
// s3:DeleteObject , s3:DeleteObjectVersion , and s3:PutLifeCycleConfiguration
// actions.
//
// Directory buckets - S3 Lifecycle 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 have
//     the s3:DeleteObject permission.
//
//   - s3:DeleteObjectVersion - To delete a specific version of an object from a
//     versioning-enabled bucket, you must have 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]CreateSession 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]CreateSession .
//
// HTTP Host header syntax  Directory buckets - The HTTP Host header syntax is
// Bucket-name.s3express-zone-id.region-code.amazonaws.com .
