Thanks--it worked, I used the first one.  As for the second, I saw the | 
operator earlier but was concerned that it won't guarantee that it 
*would* be in document order.  The XPath spec seems to be vague on 
this[1] -- i.e., whether I can guarantee document order with it, *or* it 
just so happens that they way the major XSLT implementations implement 
this operator result in it being in document order.
