I think the word "preserve" seems to indicate the original intent is that somebody has done something somewhere else to add accessibility information to the object and this checkpoint seems to be saying make sure you keep it around for use in this authoring tool. In the excel case I stated nobody really did anything special for accessibility, but there is information available that can be used to generate accessible markup. I think a term like "generate" accessible markup is a different concept than the current word "preserve". You may want to describe more the difference between "human authored" and "automatically generated" accessibility information. I would suggest this be done through checkpoints, since it seems like two fundamentally different concepts to me. I think the use of multi-media in 3.3 is limiting. Why not "pre-written" accessibility information for any object be used as the default? Is there something special about mult-media?
