The biggest problem I have tested (and left out in my first email ) is that JAWS 14 in IE9 and Firefox 20 relates incorrect heading levels for correctly coded HTML Headings in HTML5 Elements.

Coded structure:
<h1>Explicitly Ranked Headings</h1>
<nav>
<h2>Navigation</h2>
</nav>
<section>
<h2>Section</h2>
<article>
<h3>Article</h3>
<section>
<h4>Subsection</h4>
</section>
</article>
</section>
<aside>
<h2>Aside</h2>
</aside>

JAWS Heading List (FF20):
h1. Explicitly Ranked Headings
h3. Navigation
h3. Section
h5. Article
h2. Subsection
h3. Aside

Only difference between IE 9 and Firefox 20 is IE 9 drops out the h2. Subsection entirely.

So my advice would be to include the capabilities in your system, but include verbose documentation as to the current pitfalls.
