XdmSequenceIterator may incorrectly return duplicate items.

Reviewed the changes.
I think the contract for
Iterator (and the behaviour of the current

next() should throw
NoSuchElementException rather than return null.
Also, I think the comment in
next() that the exception cannot occur is wrong. I will try and construct an example.
