* It doesn't make sense to say that a <span> could carry the 
@subheading/@hcaption attribute unless you also suggest that the 
heading caption could - as well - be the child of a <hn>. (So far 
you've suggested it could be the (adjacent) sibling of a <hn>.) Because 
it is very bad coding style to let a <span> be the adjacent sibling of 
a <hn>.

* The thinking would have been undersatndable if we were speaking about 
@role="subheading". But we are speaking about @subheading/@hcaption, 
for which you said there would be minted a @role value, anyway. So, if 
A11Y is all that matters, then authors could eventually use that 
role=subheading on the span/div, rather than @subheading/@hcaption.

* @subhead/@hcaption should probably be limited to <hn> elements.

Thought experiment: can't we just use role=presentation?

<h1>Heading</h1>
<h2 role="presentation">subheading</h2>

Why not? 

If role=presenation is not possible, then justification must be that 
<h2>:

 * _retains_ its "heading-ness"
 * _looses_ its outline-ability
 * _gets_ a caption relationship to its adjacent sibling

(Additionally, to use @role=presentation would be to mix the ARIA layer 
and the HTML layer.)
