I agree that these are Good Things.  But surely they are achieved more
easily with an HTML5 to XML converter?  Given the existing HTML5 parsers,
it's easy to walk the resulting DOM and output XML directly.

Again, I agree that these are Good Things, but I think they too are best
managed without adding still another loose parsing mode.
