Action-1355: Proposed revision

For the ARIA specification, where the grid role is defined I propose the
following text change in response to this action:

Add the following text in grid role definition of the ARIA 1.1 spec:

When aria-selected="true" is applied to an element having a role of
rowheader or columnheader, that is owned by a grid with
aria-multiselectable="true", the gridcells corresponding to the respective
row or column must also expose the aria-selected state of "true", unless
overridden by aria-selected="false" on a gridcell in the corresponding row
or column.


To this paragraph:
gridcell elements with the aria-selected attribute set can be selected for
user interaction, and if the aria-multiselectable attribute of the grid is
set to true, multiple cells in the grid may be selected. Grids may be used
for spreadsheets like those in desktop spreadsheet applications.
</change>


I recommend that the text of this revised paragraph also apply to the role
treegrid.


Please refer to the aria editor's draft for the role grid:
