+/**
+        Implements the interface to the "Visitor pattern" (see the Accept() method.)
+        If you call the Accept() method, it requires being passed a XMLVisitor
+        class to handle callbacks. For nodes that contain other nodes (Document, Element)
+        you will get called with a VisitEnter/VisitExit pair. Nodes that are always leafs
+        are simply called with Visit().
+
+        If you return 'true' from a Visit method, recursive parsing will continue. If you return
+        false, <b>no children of this node or its siblings</b> will be visited.
+
+        All flavors of Visit methods have a default implementation that returns 'true' (continue
+        visiting). You need to only override methods that are interesting to you.
+
+        Generally Accept() is called on the XMLDocument, although all nodes support visiting.
+
+        You should never change the document from a callback.

+        A XMLHandle is a class that wraps a node pointer with null checks; this is
+        an incredibly useful thing. Note that XMLHandle is not part of the TinyXML-2
+        DOM structure. It is a separate utility class.
+
+        Take an example:
+        @verbatim
+        <Document>
+                <Element attributeA = "valueA">
+                        <Child attributeB = "value1" />
+                        <Child attributeB = "value2" />
+                </Element>
+        </Document>
+        @endverbatim
+
+        Assuming you want the value of "attributeB" in the 2nd "Child" element, it's very
+        easy to write a *lot* of code that looks like:
+
+        @verbatim
+        XMLElement* root = document.FirstChildElement( "Document" );
+        if ( root )
+        {
+                XMLElement* element = root->FirstChildElement( "Element" );
+                if ( element )
+                {
+                        XMLElement* child = element->FirstChildElement( "Child" );
+                        if ( child )
+                        {
+                                XMLElement* child2 = child->NextSiblingElement( "Child" );
+                                if ( child2 )
+                                {
+                                        // Finally do something useful.
+        @endverbatim
+
+        And that doesn't even cover "else" cases. XMLHandle addresses the verbosity
+        of such code. A XMLHandle checks for null pointers so it is perfectly safe
+        and correct to use:
+
+        @verbatim
+        XMLHandle docHandle( &document );
+        XMLElement* child2 = docHandle.FirstChildElement( "Document" ).FirstChildElement( "Element" ).FirstChildElement().NextSiblingElement();
+        if ( child2 )
+        {
+                // do something useful
+        @endverbatim
+
+        Which is MUCH more concise and useful.
+
+        It is also safe to copy handles - internally they are nothing more than node pointers.
+        @verbatim
+        XMLHandle handleCopy = handle;
+        @endverbatim
+
+        See also XMLConstHandle, which is the same as XMLHandle, but operates on const objects.
