You're right. An element referred by aria-errormessage can be an alert of
live region and thus should be announced by a screen reader, when it pops
up. In this case, it seems the screen reader may need to find a context
element, and if this is true, then the reverse relation is needed.

aria-details are different, since they are more like labels and
descriptions, and I guess thus they should be skipped when navigating the
virtual buffer. That suggests that aria-details either needs a role (or
xml-roles object attribute) or a reverse relation.
