That is correct. Even if you need a referenciable interface on the Dom0, 
the bridge itself is good enough.

Since your ifup-ifdown scripts could have difficulties recognizing your 
interface as a bridge (and perform the correct underlaying actions), a 
good workaround is to make it specifically manual:

auto xenbr99
iface xenbr99 inet manual
   up brctl addbr xenbr99
   up brctl stp xenbr99 off
   up ip addr add 11.22.33.44/mask dev xenbr99
   up ip link set xenbr99 up
   down ip link set xenbr99 down
   down ip addr del 11.22.33.44/mask dev xenbr99
   down brctl delbr xenbr99
