Patrick,
The only message that is required to be supported for Sub-Devices is the SUPPORTED_PARAMETERS message. This is detailed in Section 9.3.
There is no requirement for any other messages to be supported and as you point out some would not make sense. Of course there are Sub-Devices where IDENTIFY_DEVICE and SOFTWARE_VERSION_LABEL would be useful but it completely depends on the application.
