DM-BR-B compliant devices must support the features of device B. Once a
Restore procedure has been initiated on the device, the Read_Only property of
configuration File objects shall contain the value FALSE and the File_Size
property of the configuration File objects shall be writable if the size of the
configuration file can change based on the device's configuration.
If the configuration file objects are not guaranteed to exist once a Restore pro-
cedure has been initiated, then the device must support execution of the Cre-
ateObject service.

as needed for communication with other devices.
