The draft needs to be clear on which of the four modes in section 10 are mandatory to implement. I need to be clear, I'm not talking about mandatory to use, it's fine if people have a deployment that does not need to enable security or want to use a very different option. But for interoperability, we need to have something that two given devices implement in common.
