RE: Can sets have order?
>There is no query which yields visibly different results. ????? There are ***many*** Xpath expressions, which will produce different results when you swap the two nodes: 1. generate-id($node) 2. count($node/preceding::node()) 3. count($nodeset[position() < 4 and count(preceding::*) = $num1]) The above is constructed assuming that node1 and node2 are respectively $nodeset and $nodeset and that $num1 is equal to count(node1/preceding::*) The expression count($nodeset[position() < 4 and count(preceding::*) = $num1]) will evaluate to 1 given the original nodeset. It will evaluate to 0 on the nodeset in which the deep-equal nodes node1 and node2 were swapped.
