You're probably more familiar with their XML representation than I am (is
there a pointer to it you can pass on to me?), but I wonder... is there a
way to encode relationships between element (e.g. LABELED_BY)?  This is one
of the things that we have in the GNOME Accessibility architecture that I've
not seen anywhere else (well, outside of the Java Accessibility API, and
what we've defined for Mozilla and StarOffice of course).
