31 * A step iterator is used to evaluate expressions like "BOOK/TITLE".
32 * A better name for this iterator would have been ParentIterator since
33 * both "BOOK" and "TITLE" are steps in XPath lingo. Step iterators are
34 * constructed from two other iterators which we are going to refer to
35 * as "outer" and "inner". Every node from the outer iterator (the one
36 * for BOOK in our example) is used to initialize the inner iterator.
37 * After this initialization, every node from the inner iterator is
38 * returned (in essence, implementing a "nested loop").
