To my knowledge, CAM-I are the curators of this specification and are very protective of how you obtain it. The 3.0 spec goes for $80 from CAM-I. LK volunteered to put the whole thing in HTMLhelp and/or Windows help format for the user community. Initially, CAM-I agreed - later they pulled the reigns in and have gone back to an "over protective" posture.

I doubt you will find it online anywhere. Let us all know if you do!
