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
