I'm reworking it constantly -- I've added a notion of "subtree value" to
it -- the idea that an entire subtree can be visited and produce a string
which represents its "value" (alternatively, visiting a subtree can
produce side effects like populating a dictionary for use by another
subtree).

Its not terribly clean (ie, the default behavior for node's value is to
take the node's "Value" as returned by the visit method called on that
node and append that value to the value of each of the node's children.
This will basically "flatten" an XML file (The default value of a text
node is the text itself -- other nodes' default values are "").

Anyway, when I get the current version working I'll post it up at the same
URL -- http://www.aimnet.com/~gwachob/DOMVisitor.py
