Historically there has been a bit of a debate about this.  It's not
clear if the XML is meant to represent static configuration about the
domain (eg. what disks it has), versus administration of the domain
(how vCPUs are pinned for example).

Is this still a real distinction we can/need to make?  Maybe time to
revisit this and allow administrative things to be added.
