Still, I can't help but wonder if someone will try to feed the live
dumpxml output back into libvirt to define a new network config, and
trigger an rng failure as a result - you need to touch
docs/schemas/network.rng.  I also think this is missing documentation -
it may be an output-only parameter, but is worth mentioning in
docs/formatnetwork.html.in.
