aws s3 sdk代码里有大量这种代码，求教后面的** `type:"structure" payload:"CreateBucketConfiguration"`**里的标签是什么用法？
貌似是可以自定义的，具体如何自定义
```
type CreateBucketInput struct {
_ struct{} `type:"structure" payload:"CreateBucketConfiguration"`
// The canned ACL to apply to the bucket.
ACL *string `location:"header" locationName:"x-amz-acl" type:"string" enum:"BucketCannedACL"`
// Bucket is a required field
Bucket *string `location:"uri" locationName:"Bucket" type:"string" required:"true"`
CreateBucketConfiguration *CreateBucketConfiguration `locationName:"CreateBucketConfiguration" type:"structure" xmlURI:"http://s3.amazonaws.com/doc/2006-03-01/"`
// Allows grantee the read, write, read ACP, and write ACP permissions on the
// bucket.
GrantFullControl *string `location:"header" locationName:"x-amz-grant-full-control" type:"string"`
// Allows grantee to list the objects in the bucket.
GrantRead *string `location:"header" locationName:"x-amz-grant-read" type:"string"`
// Allows grantee to read the bucket ACL.
GrantReadACP *string `location:"header" locationName:"x-amz-grant-read-acp" type:"string"`
// Allows grantee to create, overwrite, and delete any object in the bucket.
GrantWrite *string `location:"header" locationName:"x-amz-grant-write" type:"string"`
// Allows grantee to write the ACL for the applicable bucket.
GrantWriteACP *string `location:"header" locationName:"x-amz-grant-write-acp" type:"string"`
// Specifies whether you want Amazon S3 object lock to be enabled for the new
// bucket.
ObjectLockEnabledForBucket *bool `location:"header" locationName:"x-amz-bucket-object-lock-enabled" type:"boolean"`
}
