Still viewing the tables at
http://dev.w3.org/html5/spec/Overview.html#annotations-for-assistive-technology-products-aria

(1)
<meter> should have a role=status, at least as a weak semantic.

(2)
<td> and <th> have the aria-labelledby set to the headers attribute.

That covers explicit and oddly placed headers.  But shouldn't it also
take the table headers algorithm into account, and get the standard
headers?
http://dev.w3.org/html5/spec/Overview.html#header-and-data-cell-semantics

If it is assumed that this would be redundant with the rowheader and
columnheader roles and automatic determination from the DOM, that
should at least be made explicit.  Also, for purposes of
aria-labelledby I assume -- but am not sure -- that the headers
attribute would replace, rather than augment any standard headers, as
it does in the table header algorithm.

(3)
Should thead and tfoot have the (abstract) role sectionhead?

(4)
Should tbody have the role of grid, or is that covered by the table parent?

(5)
For table, role must be either grid or treegrid.  Most tables in
practice are presentational, and should have role=presentation

While such tables are themselves non-conforming, I do believe that
honesty about it will leave AT less badly off.  I would therefore
suggest at least mentioning role=presentation.
