First question for the ARIA/AccName group... All three implementations fail this test, but they all fail it the same way, which usually makes me doubt my test expectation:

<nav aria-labelledby="r1" class="ex" data-expectedlabel="inception cubed" data-testname="nav with straight recursion">
  <h2 id="r1" aria-labelledby="r2">1st FAIL IF INCLUDED</h2>
  <span id="r2" aria-labelledby="r3">2nd FAIL IF INCLUDED</span>
</nav>
<span id="r3" aria-label="inception cubed">3rd FAIL IF INCLUDED</span>

Gecko, WebKit, Chromium all agree on the computedlabel here:

FAIL message: expected "inception cubed" but got "1st FAIL IF INCLUDED"

While I hope no one will write code like that in production, I believe I am reading the labelledby portion of the algorithm correctly, and that the recursion step allows chaining together references like this. Do the editors and ARIA implementors agree that the implementations are not to spec? Do implementors have concerns this recursion step of the algorithm?

Confirmed there's an ambiguity and filed issue #209 against AccName... will comment or remove that test in the meantime.
