Axis attribute

Dear all:

I've been reading a lot about the use of "axis" attribute to categorize 
and group cells, but I also have read that its support is almost 
inexistent. Does anyone know if this attribute is going to be supported 
in the near future? or perhaps in the distant future...? <wink>

I've tested it with JAWS and nothing happens, so I'm confused about its 
real usefulness.

Thanks in advance,
Ramón.
