I thought I explained my usage pretty well. You should go back and re-read it, and also take a look at the Wikipedia page I reference, where it's explained in more detail. Basically, you can name the exceptions off the top of your head, but you could never do that with the non-exceptions because they're so numerous. Kind of like how in your parking example, you don't need to name the hours that parking is allowed, because it's a rule. It's always allowed, with some exceptions. You only need to point out the exceptions. I would take your charitable interpretation and say you're misunderstanding the phrase. Since there are examples of this usage all over the Internet and a very long Wikipedia page detailing the various forms, I hope we can move past this wildly off-topic conversation.
