**Description:** If a KMS URL is set by writers, it will be stored in the key

should set the KMS URL property.
If they cannot do so, they can enable retrieving the KMS URL from the stored
key material by setting this parameter
to `true`. KMS client implementations must validate the URL value and use
authentication to prevent key material
