title: How to make screen reader announces “1of7”/“2of7” kind of information?
body: <p>I understand that by using the role="treeitem" plus aria-setsize and aria-posinset you can make the screen reader announces the position of an item in a set such as "1 of 7" or "2 of 7".</p>
  
  <p>Is there a way to do the same thing for other groups such as menu bar, or tab strip? We certainly don't want to enforce the "treeitem" role just to achieve this.</p>
  
  <p>Thanks in advance.</p>
