InfoPath Fodder from the Boneyard

I am sitting in my home office and I am (after being told so by the emperor of the house) cleaning out old stuff, sorting papers, etc. pp.   This includes checking, invalidating and throwing out a couple hundred of old CDs and consolidating all that's worth keeping. Aaaaaaanyways.... I just did something very, very scary and outrageous: I installed my PDC 2001 copy of the Hailstorm SDK to get some schema fodder for InfoPath. Uh! Oh! Where does that go?
