Bug#536701: Proposal: switch to HTML 5
It turns out it is not easy so early in HTML 5 history, but after looking
http://www.google.com.tw/search?q=validate+HTML5&ie=utf-8&oe=utf-8
I finally found
http://www.w3.org/QA/2008/08/html5-validator-beta
an HTML 5 validator
http://qa-dev.w3.org/wmvs/HEAD/
and proceeded to find genuine invalid MediaWiki HTML 5 invalidities
