Re: role="subheading" or role="subtitle" to replace hgroup

hi leif,

i would suggest

a subheading attribute only be allowed on a sibling of a Hx, otherwise its
ignored.

thats what <hgroup> is, with the subheading you get an explicit semantic to
convey to a11y APIs
i.e this is a "subheading" of its sibling heading

can anyone provide real world examples where this:

<h2>heading</h2>
<h2 subheading>subheading<h2>

would be ambiguous?
