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).
