As it stands, I believe even the text on raise states that all the spell does canonically is rouse some one from an unconscious state. Falling to 0 HP in XIV is in fact considered being knocked unconscious. The text even says exactly that.
That being said, resurrection of the dead was loosely dabbled in with the original 1.0 storyline, but seeing as that never went anywhere we didn't get final answers on it.
As it stands, though, the Thaumaturge's guild's stance on the resurrection of the dead isn't too great. At all. Since it basically equates to necromancy.
Unfortunately, canonically, bringing some one back from death isn't exactly something commonplace, let alone something that happens at all. Not saying it isn't a possibility, but it's not a simple subject by any stretch.
