My apologies James... I see that is your exact point.

It would be ideal that with text/html parsing rules apply to the
nested html markup... parser building the dom and working like: found
SVG element, parse element as XML; parsing children ... found html
element, parsing element as text/html ... and so on. The result being
a conforming HTML5 DOM.

(That's right isn't it... even when non-conforming markup is parsed,
the parsing rules are such that a conforming DOM is constructed?)
