For all problems concerning eliminating, counting, or grouping duplicates, see http://www.jenitennison.com/xslt/grouping

It's easy in XPath 2.0, of course:

   count(distinct-values(something/@type))

You can't do it the way you suggest, by incrementing counters: functional languages don't work that way.
