Ah I accidentally demonstrated the first law of Xpath:
If you are about to write  != then write not(   =  ) instead.

Of course it proves both my point 
  Yes it can be done in Xpath 1
and Dare's
  Yes it is unreadable and prone to user error without some extra set
  operation primitives.

Unfortunately as things stand to get the extra set operations
you have to get the whole of XPath 2 which means that you go from a
usable language with a few obscure quirks to something that is
completely obscure, non portable and unusable. Progress of a sort I
suppose.
