The reason why I suggested reusing <host> is because you could in
principle have socket as an attribute even for other transports.
libvirt for example has it as a socket parameter for its ssh transport.

What about moving the transport to source:

   <source protocol='gluster' name='Volume2/Image' transport='tcp'>
     <host name='example.org' port='6000'/>
   </source>

   <source protocol='gluster' name='Volume2/Image' transport='unix'>
     <socket path='/path/to/sock'/>
   </source>

where hypothetically an ssh transport could have both host and socket
sub-elements.
