 /**
  * Instances of the class {@code RecursiveXmlVisitor} implement an XML visitor that will recursively
  * visit all of the nodes in an XML structure. For example, using an instance of this class to visit
  * a {@link XmlTagNode} will also cause all of the contained {@link XmlAttributeNode}s and
  * {@link XmlTagNode}s to be visited.
  * <p>
  * Subclasses that override a visit method must either invoke the overridden visit method or must
  * explicitly ask the visited node to visit its children. Failure to do so will cause the children
  * of the visited node to not be visited.
