But only if you have some specification of the order other than "the
order in which they appear". By using "A" and "C" above you are implying
alphabetic order and so its not hard to spot B is missing but in your
example 
you said the order of the elements in the two docs could be different 
so how in that case do I know B is missing rather than just later in the
order?
