ozone/XML just uses Xalan for XPath functionality. XPath can only query (read)
DOM. There is no standard XML 'update' language yet.

Just call the 'update' DOM methods you need. Each node is a database object.
The database sets locks implicitely and finds out what and when to store.

See samples/XML/Query.java. The result set is printed between explicite
transaction boundaries.
