one point to consider in regards to the following statement that is being
quoted

"Although highly recommended by some webpage designers as a way of
summarizing the contents of a table, the "summary" attribute of the TABLE
tag is not sufficiently supported by major assistive technology
manufacturers to warrant recommendation."[1]

this advice was last updated "*June 21, 2001"*, the summary attribute is now
and has been supported by the major assistive technology manufacturers
(freedom scientific & gwmicro) for some time.
