I don't have any technical problem with using CC to specify the century separately ... although I do wonder why anybody would want to do so. Apparently ISO 8601 isn't explicit about how years earlier than 1 AD might be handled, because the standard is only designed to support dates going back as far as 1582. However, the basis for "week date" years is supposed to be the same as that for Gregorian years, so I guess BC could work the same way in both systems. Short version: I think using CC and AD/BC in combination with week dates would be downright weird, but I don't object to the patch.
