I suspect it's a matter of convenience: If you have a reference to the cell, and it can provide the row/col, you're done. Otherwise, you have to walk the tree to find the relevant row that provides that information. The same sort of quick access applies in the case of aria-setsize. You're right that aria-setsize looks like a property of a list, not a item within the list. But, again, the code avoids the step of walking the tree to determine the relevant ancestor that holds the set-size information if the item has that info at hand. -- ;;;;joseph.
