 Description   

Current APIs are not expressive enough for application to describe what sort of changes they really want to receive notifications for.

Since our data store is essentially an XML document, XQuery is the logical choice for the expression language. In order to implement this, though, we need not only an API, but also a default NormalizedNode-based implementation.

It seems like this should also include the functionality described in BUG2300. That is, we should support XQuery for both one-off queries as well as listener-style streaming queries. Is that something we could easily include in this enhancement?
