Not sure I understand the question James... I don't think anyone is
proposing this table for any of our techniques... it is simply a test
table...

I had several action items.
1) Check hx in a table 
2) Check what is reported to an API when there are two level of <th>
3) Check the behaviour with and without the scope
4) Check what AT reads two layers of table <th>without ids, headers

Sailesh produced a table for the tests which I tweaked to make it validate
and tested using my full morning to do so. 
I think h63 was a smaller part of the discussion as I understand it.
But just for thoroughness I have done the same test with h63 example code,
and have added it to the page, as well as the results of the testing.
In JAWS the scope is necessary to prevent all the row headers above a row
header from being read hen tabbing into the row header column, and the same
for column headers. This appears to be behaviour just in JAWS and not in
NVDA, or Voice Over. 

I hope that these tests fulfill my action items, and informs the group
regarding:

1) the outstanding issue of <hx> headings in a table
2) recommendations about the necessity or non-necessity of scope on simple
tables
3) the question about two lawyers of headings reading fine in both JAWS and
NVDA without headers and ids

If we are discussing modifying H63 to include scope shouldn't we use a
simpler table than the example (one without these extra H3 cells in the
table)?

Regards,
James
