I think it's a really bad idea to combine a collection and an iterator over
that collection in a single object. It means that when you have a method
that takes two collections as arguments and compares them, the method fails
abysmally when you compare a collection to itself.

(Sadly, the people developing the XQJ API seem to be making this mistake).
