If there are differences, they should be documented in those docs.

Honestly, the best way to get documentation fixed is to send a patch or
edit the wiki.

Nope, that's not true - set up e.g. br0 as described in the doc and then
for each guest do:

  <interface type='bridge'>
    <mac address='...'/>
    <source bridge='br0'/>

each guest will have a tap interface added to the bridge
