Well, they seem obvious to me, too, and I wasn't on the design team. I'd bet that most people who aren't trying to game the system settle on the 'obvious' reading.
In general I agree here. A lot of the time people try using intuition or other reasoning to bend (whether intentionally or not) the rules as written. They did a fairly good job this time around with being precise in their wordings. That is not to say there arn't vague rules or things, we know there are. The only reason to think CC attack is an OA is from the feat table, which is very likely a holdover from a previous iteration of rules development. Anyways text overrides tables, in general doesn't it? That was at least the case in 3.5...
