revised table headers design is OK, right?

We have been tracking a table-headers issue-20 since 2007-11-21:

"The table headers algorithm currently in the HTML 5 spec does not deal
with some common table formats ..."

 -- http://www.w3.org/html/wg/tracker/issues/20


One of the WCAG 2 techniques demonstrates a common table format
using th/@headers, which, as of last June, wasn't allowed in HTML 5.

  @headers on th too or just td?

  -> http://www.w3.org/TR/WCAG20-TECHS/H43.html

The attached test case is derived from H43 (by machine; see
Makefile and extract-ex.xsl for details). validator.nu used
to complain about th/@headers; it no longer does...

The editor revised the design in December:

4.9.11 The th element

As far as the chairs and I can tell, this new design addresses
the concerns related to issue-20 (though not the summary
issue, issue-32), so per ACTION-72 I propose the WG adopt the 20 Dec
design for table headers. Does anyone object?

I suppose it would be useful to follow the 'three independent'
pattern; I count the editor(s) and myself as two.
Chaals, perhaps you'd like to confirm that you agree?
Or Ben? Cynthia?
