I don't think so, if we have e.g.
then with
$users[not(. = $friends)]
we select those User/UserId elements for which there is no Friend/UserId
with the same value while
$users[. != $friends]
selects those User/UserId elements for which there is at least one
Friend/UserId element with a different value.
:) as I say, it always takes a while to get it, if at all......
