A11Y tests in summary comparison table

For users and testers of non-visual media on this list, I wanted to 
mention that my comparison table has these accessibility 
features/issues:

a) a summary attribute (with content)
b) axis attribute on all data cells 
c) a 'table info section' inside the caption. (Not my proposed 
tableinfo element - merely a span element with a CSS list 
(display:list-item) inside.)

The axis attribute is meant as replacement for the simple color codes 
used in the table - would be interesting to know if it is supported 
e.g. in Jaws? Of course, axis is currently not supported in HTML5.

The 'table info section' is meant as a unpretentious test of whether 
having such info inside <caption> (which HTML5 permits) helps or hurts 
(or neither).
