Thanks for reviewing this (and sorry for the delay -- I was on vacation,
and blissfully unable to read email).

I'm happy (and a little surprised) that there's no comment here about the
HTML parser changes. Is that because it all looks good, or because you
didn't dig that deep into it yet?

The XML/XSLT/XDM stuff is missing only because we didn't have time to get
to it yet. It's next on my priority list now that I'm back. The spec bugs
for describing the additional semantics are included inline below.

Also, FYI: Although we've landed code for the current spec in WebKit and
Chrome Canary, it's behind a compile flag, only enabled for the Chromium
port and will not go to beta or release until the spec is reasonably
settled (including the XML/XSLT/XDM stuff).
