[whatwg] self-closing tags in html5

I see browsers doing this, but I have not seen sites doing it.

Does anyone seriously think that "<foo/>" is an ordinary open tag?

The question is not whether it has happened but whether it has been
done deliberately and systematically in significant quantity.  Do you
have evidence?

If "<foo/>" in the html namespace is to be an error, then the html5
spec needs an explicit statement of how the error recovery should
happen.

Right now I'm seeing DOMs built from <x><foo/>...</x> that serialize
to leapfrogged tags, i.e., <x><foo></x></foo>.  For example:

Html5 DOM building from text/html will be hard enough without the
syntactical schizophrenia of 8.1.2.1 (6).
