Whether RFC 2854 allowed pre-HTML4 content is an interesting historical 
question, but not the primary one.

What's important is whether the new text/html will allow existing HTML4 
content to stay valid; content including things like @profile, for 
instance. Right now it doesn't, and I believe that is a problem.
