Thank you, Mr. Chair.
I'm not sure that “may” is better than “should” as the operative word. It isn't giving permission to work to ensure consistency; it's more providing direction and saying that this is the goal that we are looking for, but it doesn't prescribe it.
I agree that “must” is far too rigid a word, but I would suggest “should” instead of “may” because I think that's the intent of the amendment as well.
