-
-	If you return 'true' from a Visit method, recursive parsing will continue. If you return

-

-	visiting). You need to only override methods that are interesting to you.
-
-	Generally Accept() is called on the XMLDocument, although all nodes support visiting.

-/** XMLNode is a base class for every object that is in the
-	XML Document Object Model (DOM), except XMLAttributes.
-	Nodes have siblings, a parent, and children which can
-	be navigated. A node is always in a XMLDocument.
-	The type of a XMLNode can be queried, and it can
-	be cast to its more defined type.
-
-	A XMLDocument allocates memory for all its Nodes.
-	When the XMLDocument gets deleted, all its Nodes
-	will also be deleted.
-
-	@verbatim
-	A Document can contain:	Element	(container or leaf)
-							Comment (leaf)
-							Unknown (leaf)
-							Declaration( leaf )
-
-	An Element can contain:	Element (container or leaf)
-							Text	(leaf)
-							Attributes (not on tree)
-							Comment (leaf)

-/**
-	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.
