I'm not opposed to opening an ARIA 2.0 issue for adding a "mixed" state for aria-selected, but you'll be able to sell the idea better if you come up with a real-world scenario where this might be useful. Many cases would/could be covered by nested menus with groups of menuitemradio elements.

The ARIA spec indicates that the "aria-multiselectable" property can be used with the the "tree" role, and the "aria-selected" state with "treeitem". However, the "aria-selected" state only accepts a boolean. How should developers indicate parent nodes in a partially selected stated - some tree items selected, some not. And how is a screen reader supposed to announce the partially selected state of a parent node? > > I've yet to find any ARIA TreeView examples that make use of "aria-multiselectable", but considering the spec indicates that it applies to trees and the ARIA Authoring Practices specifies keyboard shortcuts for supporting multiple selection on trees, I figured some thought must have been given to this use case. > > Any insight would be greatly appreciated. > > Thanks, > Todd
