Do we really need such verbose XML. At the very least the 'num' attribute
is redundant, since you can trivially do count(/topology/cells/cell) or
count(/topology/cells/cell[ id=0]/cpus/cpu) XPath exprs in both cases.

The addition of extra tags every time we have a list is not the style we
have normally used in libvirt. eg, we don't use


to surround the list of disks in a domain.

I'd prefer to see it looking more like this:

     <cell id='0'> 
       <cpu id='0'/>
       <cpu id='1'/>
       <cpu id='2'/>
       <cpu id='3'/>
