/**

 * <code>DTMIterators</code> are used to step through a (possibly
 * filtered) set of nodes.  Their API is modeled largely after the DOM
 * NodeIterator.
 *
 * <p>A DTMIterator is a somewhat unusual type of iterator, in that it
 * can serve both single node iteration and random access.</p>
 *
 * <p>The DTMIterator's traversal semantics, i.e. how it walks the tree,
 * are specified when it is created, possibly and probably by an XPath
 * <a href="http://www.w3.org/TR/xpath#NT-LocationPath>LocationPath</a> or
 * a <a href="http://www.w3.org/TR/xpath#NT-UnionExpr">UnionExpr</a>.</p>
 *
 * <p>A DTMIterator is meant to be created once as a master static object, and
 * then cloned many times for runtime use.  Or the master object itself may
 * be used for simpler use cases.</p>
 *
 * <p>At this time, we do not expect DTMIterator to emulate
 * NodeIterator's "maintain relative position" semantics under
 * document mutation.  It's likely to respond more like the
 * TreeWalker's "current node" semantics. However, since the base DTM
 * is immutable, this issue currently makes no practical
 * difference.</p>
 *
 * <p>State: In progress!!</p> */
