<P>
A Watch represents a class that is interested in looking at nodes for the purpose
 of evaluating uniqueness and key constraints. A SelectorWatch looks for the nodes
 that match the selector in a unique, key, or keyref constraint. There are two
 concrete subclasses: one for key/unique, the other for keyref
