+1, looks like a simple solution that might do the job.

+1, I like this approach however it may confuse our users a little bit.
Maybe we should have a flag in configuration (disabled by default) which
would enable persisting changes back into xml?

+1 for writable attribute. This would fix nicely into configuration
listeners. How about exposing new Configuration MBean with all writable
configuration attributes?
+1 for staying symmetric with our solution.
