The optional write-only UpdateKey Object can be used if the underlying system requires some key to unlock the update feature. The format and where to get the key is vendor-specific and not described in this specification. If UpdateKey is supported, the Client shall set the key before the installation. If the PrepareForUpdateStateMachine is used, the UpdateKey shall be set before the Prepare Method is called. The Server shall not keep the value for more than one update.
