You don't *have* to include a damage type. And, as an FYI, bleed isn't a valid damage type in the 3.5E/PF ruleset (see the discussion on this in the previous page of this thread). You can still include it for information, but FG won't doing anything with it. Otherwise, the DMGO examples are correct for using dice with the DMGO effect.
JerryRig - DMGO is just for hit point damage, there is no ongoing ability damage effect.
