New damage types:

With the new 1.17 BETA there is a new trigger: Unit - Damage Target, and also Unit - Damage Area, with these triggers, you can choose damage type, however, except for the normal damage, there are a whole lot of other damage types:
Unknown, Enhanced, Fire, Cold, Lightning, Poison, Disease, Divine, Magic, Sonic, Acid, Force, Death, Mind, Plant, Defensive, Slow Poison, Demolition, Spirit Link, Shadow Strike and Universal.

I mean, I can guess some of these, but what are they good fore, has anyone found some way of using this, with triggers or anything like that, since I have looked around some, but haven't really found anything for it. Would really appreciate any help.
