I think this makes sense. Would this be affected at all by equality
of text strings, taking into account locale? Or would there be
equality for text in each locale (so oprlsortop and oprrsortop would
always be not only the same type (text) but also of the same locale)?
I'd think this is would be the case so it wouldn't end up being a
problem.
