UnitClassification()?

[acapela]

i have always known i am too literal-minded for my own good... but i am going to ask anyway.

does the UnitClassification() API function return "worldboss" for ALL types of bosses (both "world" bosses AND instance/raid bosses; i.e. the sort of thing that would show a player at the level cap a skull on its unit frame)?

i assume so, but i have not yet been able to find a clear statement to this effect or a clear code example, so i figured i would ask.

if this is not clear to folks, can anyone think of an instance i could use that would have a 73+ boss right at the front as the first pull? i could sneak in stealthed and do some testing.

thanks in advance for any information.
