Hi Ian,
> <Hixie> table headers: i haven't yet seen a clear description of the problem, but if there is a problem, then we'll have to address it


Current AT's do not support the HTML5 way of associating header cells
and data cells. But they do support id/headers.

This means that complex irregular tables cannot be marked up in HTML5
to provide current AT's with the required information about
relationships between headers and data.

So in order to support AT's that do not implement the HTML5
algorithms, authors who want to use HTML5 will be forced to write
non-conformant code.

more inf from laura:

Joshue O Connor, Gez Lemon and I have completed the deliverable for
Action 72. It is at:

We request that the definition of the headers attribute in the spec be
extended to allow it to reference a td. This would make it possible
for complex data tables to be marked up accessibly.

The headers/id markup is functional and works today. Results of some
recent testing:
