Here is a sample .xsd class based on a few quests and random events (which are also quests). I've also generated a C# file from it.
Hope it helps. I am going to make a Quest "Wizard" in the near future and this is my start, but if someone else wants to make a run at it here is a good place to start.
Stardock Employees feel free to give us hints/corrections if we have missed something. Thanks!
