Re: Another Draft of TAG position on use of unregistered media types in W3C Recommendations

I find it somewhat disturbing that we appear to  be taking a
position with respect to telling groups what to do namely,
"Attempt to get all types you used registered with IANA"
-- but then step back  when it comes to saying what a group
should do if the above fails. I believe it is fair for us to say
"You cannot create new types unless you register them
appropriately" --- 
but I'm not comfortable with our   guidance to WGs on
pre-existing unregistered types.
