Let me see ... Reading ARIA ... I cooked up an example of how Aria-sort="" is intended to be used: <table> <tr><th aria-sort="descending">1</th></tr> <tr><td>Z</td></tr> <tr><td>A</td></tr> </table> Above, the aria-sort value tells the user that in this table, all the "Items are sorted in descending order by this column." [1] One difference from my what my @definesorder idea is that @aria-sort is more specific (since it describes what kind of order - "ascending/descending/other") than I suggested. Another difference is that aria-sort="" should be applied to a column TH heading cell or row TH heading cell, while talked about using TR and COL. Thus I agree that aria-sort="" is basically very similar to what I suggested. Using aria-sort="" as a way of informing about the orientation thus seems possible. Only possible thing: What if it is not clear what kind of order, but it is still clear which column? >> It seems like using a row or column in the table to define order is less >> presentation-specific, and more based on content in the specific table >> instance.
