A SequenceIterator is used to iterate over a sequence of items. An AxisIterator is a SequenceIterator that throws no exceptions, and that always returns nodes. The nodes should all be in the same document (though there are some cases, such as PrependIterator, where this is the responsibility of the user of the class and is not enforced.)
