Here's a pattern I've seen repeated. Congress will pass some piece of legislation purporting something like "all persons must xyz by midnight Nov..." Then someone starts shouting "HOW CAN THEY DO THIS?" an invariably starts a "write to your Congressperson today" campaign.

But the reaction among the suitors is very different. That reaction is almost like "Oh no big deal, it's not positive law; doesn't apply to me." This area of positive law - published in the Federal Register - is not entirely clear in my mind. I'd appreciate if you suitors could elaborate on this.
