 Ah, this breaks my design. I guess

   <disk>
     <pr>
       <source type='unix' path='/path/to/qemu-pr-helper'
mode='server'/>
     </pr>
   </disk>

 is pure madness, isn't it? 
Yes, but OTOH if libvirtd starts the daemon, nobody cares about the
source type, so perhaps

   <pr driver='helper' mode='shared'>
     <source ... />
   </pr>

(mandatory source) vs.

   <pr driver='helper' mode='private'>
     <path>/path/to/qemu-pr-helper</path>
   </pr>

(optional path, default from global configuration) vs.

   <pr driver='passthrough'/>

(no helper)?
