Hi All,

I would say No to:

"Place all content within HTML5 semantic container tags, specifically article, aside ,nav, section, figure, figcaption, footer, header, and main"

Because the HTML5 outline algorithm (http://dev.w3.org/html5/spec/sections.html#outlines) is not supported by all adaptive technology and Web browser combinations. Therefore, if you use the sematic tags you will end up with an incorrect heading structure in some cases and not others. I just tested with JAWS 14, NVDA 2013, Voiceover on IE9, FF 20, Safari 5. NVDA and Voiceover both had issues. Thankx.
