Agree with Michael, The essence of this work is test specification limited for IoT devices and the focus is functionalities test within the device. I think it will be more useful to test network device and MUD controller/manager. If SG11 agrees to do this, any outcome of this work item should also been reviewed by BMWG in IETF. BTW: Who will be the consumer of this test specification? Test Instrumental manufacturer?

The work that has been described would seem to nearly impossible to do. Certainly very difficult to do in a black-box testing scenario. In order to verify *compliance* of a device, it will, I think, be necessary to convince the device to actually *do* all the things that it can. Then observe if the MUD file actually allows all those things. Aside from the difficulty of getting vendors to produce MUD files *at all*, I have no idea how SG13 plans to convince an IoT device to do all its things. So my liason reply would be: "Sounds great.
