/**
* This interface defines two signatures of the visit method; one
* taking a Node, the other a Property. When an object
* implementing this interface is passed to {@link Item#accept(ItemVisitor
* visitor)} the appropriate visit method is automatically
* called, depending on whether the Item in question is a
* Node or a Property. Different implementations of
* this interface can be written for different purposes. It is, for example,
* possible for the {@link #visit(Node node)} method to call
* accept on the children of the passed node and thus recurse
* through the tree performing some operation on each Item.
