Please clarify how QNames in the role attribute are mapped to URIs.

Maybe it's already there and I'm just reading too fast? In any
case, for motivation, the March 2004 TAG finding, which concludes...

"Where there is a compelling reason to use QNames instead of URIs for
identification, it is imperative that specifications provide a mapping
between QNames and URIs, if such a mapping is possible."
