After some discussion with Daniel Veillard, I've evolved this into:

       <!-- etc -->

(This reason for this is to be consistent with the features listed in 
<domain> descriptions).

Also after discussion with DV:

          <!-- <model> etc. as above -->

(The reason for this is to reduce the verbosity of the XML and to allow 
other guest-related non-architecture-related sections in a future version).
