Null

case object Null extends MetaData

Essentially, every method in here is a dummy, returning Zero[T]. It provides a backstop for the unusual collection defined by MetaData, sort of a linked list of tails.

It's be nice to make these final, but there are probably people out there subclassing the XML types, especially when it comes to equals. However WE at least can pretend they are final since clearly individual classes cannot be trusted to maintain a semblance of order.
