Just remember this: read the TA the way you would any TA coming from 9E. Read it as if you were management trying to get out of any language that would make your life more difficult while at the same time enforcing language that makes it easier to run the airline. Look for the loopholes.

If you find yourself saying things like "Well, I guess what they mean is this" or "Yeah, but they probably won't interpret it that way," then back away.
