/**

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.
