> Robin, how is your proposed solution compatible with incremental parsing?

As far as I could work out, here's what happens. If the document is clearly
XML, and the root element isn't "html", then if it matches something for an
external handler like Atom, it might be dispatched off to that. If however it
doesn't match that the browser seems to just parse, parse, parse and render
nothing. If at some point it suddenly sees an HTML/SVG/MathML element, it will
render accordingly (applying the default UA style sheet and all). If it reaches
the end without having seen one such element, then it shows the tree view. I
tried this out by feeding browsers some megabytes-long document.

I'm not sure how that could hurt incremental parsing, though I'd be happy to
learn. It certainly hurts incremental rendering (of XML documents that have no
HTML content) but this doesn't not strike me as a huge problem.
