<I was trying to use "preceding-sibling" to figure out if the previous sibling
***in sorted order*** had the same district, but I've now figured out after
reading on the subject that "preceding-sibling" does not operate on the sorted
tree - instead it operates on the original tree that is in "document" order.

Could you tell me where you've read this about "preceding-sibling"?  I'm a
newbie as well and haven't read this so far in any of the 4 XSLT books I have.
In fact, Doug Tidwell's "XSLT" (O'Reilly) contains an example of grouping that
seems to contradict your statement (p. 139, "Grouping Nodes").
I have an XSLT that depends on preceding-sibling working with a sorted node
set, so I would be very interested to know if what you say is true.  Thanks.
