Ian, Sub-checkpoints is possibly a misnomer, in conversations I've had with potential implementors of the checkpoints, they frequently ask "what is meant by this for my application, can you be more specific?" The goal for the guidelines was that they have good longevity, that we don't need to change or update them every six months. Therefore they needed to be somewhat independent of present technologies. The techniques are a technical note and are therefore much easier to update. So the criteria I described would explain " what does this mean right now in a practical sense with the technologies under development." It would also be more explicit for people who don't have the context or the background information needed to fully understand the intent of the checkpoint. The criteria would not add new requirements or even new information, they would simply be more explicit.
