In ARIA 1.1, focusable separators (e.g. those functioning as adjustable window splitters in a web app) support the aria-value* properties. This does not appear to be implemented for Safari or WebKitGtk. As per https://rawgit.com/w3c/aria/master/aria/aria.html#separator: The implicit value of aria-valuemin is 0. The implicit value of aria-valuemax is 100. The implicit value of aria-valuenow is 50.
