[BA] Agree that it should not be normative. However, the point about
subjectivity still applies. I’m not sure what value the SHOULD NOT
provides, even if it is in lower case.  For example, is it “difficult” to
ask to receive American English in audio but to send ASL in video or
American English in text, because the user is speech-impaired, but not
hearing-impaired?  Isn’t the whole point of the negotiation to determine
what languages can be mutually accommodated?
