I think it's a question of an overall framework. Getting into all the minutiae may run the risk of overly cementing and therefore removing some of the flexibility. It's difficult for us to deviate from what has been written down. It's human nature. I think it's possible to have an overall framework and general guidelines, but each jurisdiction's details will inevitably change in a few months or a year or two, depending on the circumstances. And the circumstances are always different. No two events are identical. Even if there were a written opus, we would still be calling the various departments in the federal government and each other for advice and examples on the tinkering that I don't think one would realistically write down.
