Smith,
FWIW, this text is also part of the information Apple published to the CUPS IPP implementation documentation:
https://github.com/apple/cups/blob/master/doc/help/spec-ipp.html
I'll work up a rev version of the registration, maybe in time for the Dec 5th concall, that incorporates this into the attribute definitions as well as the security considerations (which currently only talk about authentication but not the secure channel stuff...)
Thanks for catching this!
