As I mentioned before, Berkeley DB XML has sub-document level locking in 
the form of page level locking with user-configurable page size.

Talking about "node-level locking" is a bit of a red-herring - what you 
should be interested in is sub-document granularity locking, which in 
itself is only a means to achieve high concurrency in writes.
