Any management tool that relies on an x- prefix name is broken. We've
explicitly documented that the x- prefix is unstable and liable to go
away with a future release. Any management app that wants to use a
feature beginning with x- should FIRST push hard to get the x- removed
and stabilize the interface (and libvirt, at least, does just that).
