Yes, that point has been brought up before in the past.  Snapshot names
are another culprit.  But it should be a separate patch, per hypervisor;
I agree that this patch allowing the XML to be permissive makes sense
(since the RNG can't enforce hypervisor-specific restrictions).

ACK.  Nit - although XML allows space before />, we typically haven't
been using it, so I would have written <data type='string'/> without the
space.
