This feature allows for ARIA relationship attributes to be reflected in IDL as element references rather than DOMStrings.


This would allow specifying semantic relationships between elements without the need to assign globally unique ID attributes to each element which participates in a relationship. Moreover, this would enable authors using open ShadowRoots to specify relationships which cross over Shadow DOM boundaries.
