The semantics of HTML are a key part of how user agents have to handle
HTML. Having two separate documents isn't optimal either.

As I've said before, I'm no fan of these requirements either. But the only
way I can see of making the "break HTTP" rules as narrow as possible is to
have them be tied as closely to possible to the elements that require the
rules to be broken. I don't think it would make sense for the HTTP spec to
mention HTML elements -- it's better for specs to step on each other from
above than from below, as it were.

Yes, that's what we're doing.

Because if I didn't, then we'd probably have two conflicting specs, and
that would be confusing to a lot of people. And also, because it's just
generally the Right Thing to do. It's just not absolutely required.

Likely, yes. I don't particularly expect it to change anything though. :-)
After all, the HTML working group is also biased towards the browser
vendors, to the point where the charter says the group should be
reconsidered if the browser vendors pull out...

I have my hands full with HTML5 as it is. However, I'm on the HTTP mailing
list, and would be happy to give support for anyone who wanted to champion
pragmatic changes of this nature.
