The concept of label or legend appears to be missing from ARIA Roles

Hello,

I'm in the process of investigating annotations to XHTML documents that
can be used to facilitate both client-side scripting and accessibility.
So naturally I turned to ARIA 'Roles' and 'States and Properties'. But,
the first thing I noticed when attempting to mark-up labels and
read-only values is that there is no label and/or legend role, the
nearest thing I can find is the 'wairole:description'. Should I use the
description role like this:

<span id="foo" xhtml10:role="wairole:description" title="Image
id">Id</span>
<span xhtml10:role="wairole:input" arai:labelledby="foo"
aria:readonly="true">0901047880012b9b</span>

It strikes me that the aria:labelledby property alone doesn't say enough
about the referenced span to indicate that it is a label and the
wairole:description role is too broad.

Is there a case for having a wairole:label as a subclass of
wairole:description in the same way as wairole:tooltip?
