I have always wondered if they stacked? For example if I had all of the following on my WD:
10% bonus damage to elites from Sun Keeper
5% bonus damage to elites from my Mojo
3% bonus damage to elites from Unity
30% bonus damage to elites from Stone of Jordan
10% bonus damage to demons from Tyrael's Might
7% damage added to poison from Zuni Boots
Does that mean if I use poison abilities on an elite demon it will do 65% extra damage?
Im sure I forgot a few items for other slots but you might be able to get close to 100% if you can get other bonus items for more slots. That would just be stupid OP and Im wondering if Blizzard has a soft cap on bonus damage where after a certain point it either doesnt work or just scales horribly?.
It's nowhere near OP because all these items are not necessarily BiS. For example, for wizards even a perfectly rolled Tyrael's will never be as good as a Tal Rasha armor. Unity can have pretty amazing stats if you're lucky, but to my knowledge it can't roll trifecta. And keep in mind that even on Alkaizer runs you're fighting elites for only about ~10 of the time, most of the time you'll just see white mobs along your way - all the bonus vs elite doesn't give you any benefit there.
An interesting sentence: "We realize the current wording for this affix can be confusing, and it's something we'd like to make more clear in the future."
Damnit, this post is two months old. How long can it take to rename an affix?
Yes, damage bonuses stack. In addition, different damage bonuses seem to be multiplicative while bonus damage of the same type is multiplicativeadditive. For example, if you have 1 piece with 50% bonus damage to elites and another with 50% bonus damage to elites, you would have 100% bonus damage to elites. If instead the second piece was 50% bonus damage to demons, then against demon elites you would do 1.5*1.5 = 2.25 of your normal damage, or you'd get 125% bonus damage.
Some of the different bonus damage types include damage to elites, damage to slowed mobs (dh passive I think), damage to chilled mobs (wizard passive), bonus damage (buff type spells, like Magic Weapon for wizards), damage to demons, and the affix that says something like "Cold skills do xx% more damage". The zuni boots affix is treated a little differently, as others have stated, but it is similar in that those type of affixes are added before determining the bonus damage, even if the affixes are different elemental types, like fire, arcane, cold, poison, etc. The only real difference is that it only applies to the physical damage you do, so weapons with +arcane damage or any other elemental type won't benefit from those affixes as much as one with just +min/max damage.
EDIT: accidently said multiplicative instead of additive for damage of the same type, and corrected above.

Is that so? "Seem to be" is fair enough especially when you say it (you're the theorycrafting master around here), but is there some actual proof?
I always read about the "18% dmg increase by Triumvirate" but it would actually be 19% then (for perfect rolls). Very interesting. Too bad that my current weapon has 80% of its damage from a lightning affix...

I'm not sure how you get 19% from a triumvirate when the max is 18 (6% per and 3 affixes). But with a max roll on all 3 affixes, with no other sources of that affix and a purely physical weapon, it will increase your dps by 18%. My basis of the multiplicative nature of the various damage types comes from some analysis done by a DH in the theorycrafting forums. I'm not sure what the original post was about but the DH did some testing with various stats, including something with +damage to elites and the DH passive that increases damage to slowed mobs, if i'm remembering correctly. The conclusions were that all the different damage types were multiplicative.
It's actually fairly easy to test if you have different pieces of gear with various damage stats. You just need a low level weapon with a small damage range and a ring or amulet with as much or more min damage than the difference between top and bottom damage of the weapon. That will make the weapon deal the same amount of damage with every attack. Then just swap in and out the appropriate items and compare the resulting damage.
Oh, the second multiplicative should be additive. The example for that is Magic Weapon, Glass Cannon, and Sparkflint. They all just "Increase damage by x%", so they're the same damage type, namely bonus damage, and it is additive.

Damage bonuses of the same type stack additively, and different types are multiplicative. so your setup gives you 48% bonus damage to elites, times 7% extra physical dmg as poison, times 10% extra dmg if you are fighting a demon. So assuming you are fighting a demon elite mob with a weapon that has all physical dmg (ie not poison dmg or something) you are doing 1.48*1.07*1.1=1.74 ie 74% extra damage to that mob.
I'm not sure how you get 19% from a triumvirate when the max is 18 (6% per and 3 affixes).
isn't that 3 different types of elemental bonus damage and thus 1.06 * 1.06 * 1.06?
They add, sorry for the missleading misprint in my post, which has since been corrected. Even with different elemental affixes they all add, so for a triumvirate you'd get 18% bonus damage from all 3 having 6%. Another 8% from zuni boots again adds for a total of 26%, etc.
