     * **Directory buckets** - When you use this operation with a directory bucket, you must use virtual-hosted-style
     * requests in the format `*Bucket_name*.s3express-*az_id*.*region*.amazonaws.com`. Path-style requests are not
     * supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format
     * `*bucket_base_name*--*az-id*--x-s3` (for example, `*DOC-EXAMPLE-BUCKET*--*usw2-az2*--x-s3`). For information about
     * bucket naming restrictions, see Directory bucket naming rules [^1] in the *Amazon S3 User Guide*.
     *
     * **Access points** - When you use this action with an access point, you must provide the alias of the access point in
     * place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests
     * to the access point hostname. The access point hostname takes the form
     * *AccessPointName*-*AccountId*.s3-accesspoint.*Region*.amazonaws.com. When using this action with an access point
     * through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more
     * information about access point ARNs, see Using access points [^2] in the *Amazon S3 User Guide*.
     *
     * > Access points and Object Lambda access points are not supported by directory buckets.
     *
     * **S3 on Outposts** - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on
     * Outposts hostname. The S3 on Outposts hostname takes the form
     * `*AccessPointName*-*AccountId*.*outpostID*.s3-outposts.*Region*.amazonaws.com`. When you use this action with S3 on
     * Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name.
     * For more information about S3 on Outposts ARNs, see What is S3 on Outposts? [^3] in the *Amazon S3 User Guide*.
