ASCII is a protocol with-in itself, so there is no question about "a 
protocol be in ascii".

>>> The difference between protocol parameters and domain names is domain names are meant for human consumption, while protocol parameters are arbitrary strings of ASCII or UTF-8 text. A protocol might use the string "kritisch" to mean "something critical." Great -- people building user interfaces will read the RFC, know that parameter is "kritisch" and will display "critical," "crucial," "krytyczny," or whatever is appropriate for the user. For that matter, one could really use the string "foobar" to mean "something criticial" or even the number 42. The protocol will work just fine, and users (who do NOT read what is on the wire) can have a great experience.
