Elimination of duplicates is generally discussed under the heading of
"grouping": see under grouping in your favourite XSLT textbook, or at
www.jenitennison.com/xslt/grouping.

(Essentially, you need to do the first part of the grouping problem,
which is to select the distinct nodes; you might be able to skip the
second part, which is finding all the duplicates of each distinct node).
