Apologies, I've let my final semester stand in the way of my  
obligation to all of you. I've been in contact with the IETF, and  
resubmitted the updated draft today. I screwed up some dates, versions  
in the draft, but the current submission should be accepted and ready  
for uri review. I'll be pushing the draft into uri-review as soon as I  
hear back from the IETF secretary.

I agree, but that means that about: can't be standardized until HTML  
is standardized. Unless about: has no HTML-specific origin policy at  
all, this section is just going to beg questions.

Since about: is really designed for application-local resources, it  
seems reasonable to leave origin policy to more application oriented  
specs. Of course, since the only apps that actually implement about:  
uris are browsers, that's just a pedantic strawman.

So the frame becomes, is it worthwhile to have an application agnostic  
position? If so, is it possible to spec the origin policy free of  
HTML5, or should it say nothing? Otherwise, how does the spec remove  
reference to a changing HTML5 spec without cramping HTML's style?
