Hey Bryan,

In the past I came across some incidents in which I needed a header in
place, but couldnšt really use the <h> tag, instead I used ARIA and it
worked seamlessly in JAWS, NVDA and VoiceOver.

For example: <span role="heading" aria-level="2˛>This text will be read
and identified as a level 2 header</span>, just the same as if it was
enveloped within <h2>Š</h2>.  You can use it in a <div> or <span> and it
validates too.
