Just a simple thought, but one other vehicle for extensiblity is/could 
be MIME.

For example, in the following html5, which would be served as 
text/html, @type could certaily give the browser a clue that it was 
dealing with data that at some level could be considered at least 
providing an intention that the contained code could be considered to 
be a nested context. In the case of MathML and Ruby, I am thinking 
they are integrated closely into the browser and thus need no special 
recognition.

Again, I say served as text/html because it is the author's intent is 
that the browser plow through it and do the best it can, not necessary 
halting for 'simple' problems. If I wanted to find all problems I 
serve it as application/xhtml+xml and use all the latest XML aids.

Anyway, just tossinig this in in the spirit I saw in the HTML5 intro 
at http://vimeo.com/6691519
video and little production value.
