That's interesting... So you can use not(A!=B) to check if all nodes in
two node-sets A and B are stingwise identical; Now isn't this a good use
of '!=' ?
not(A!=B) is true just if A!=B is false which is only the case if every
node in A is equal to every node in B. If that's what you want to test
for then the expression is put to good use, but it's rather rare to have
a node set where all the nodes are string equal (unless it's something
like @abc where you know there is at most one node in the set).
