1. In a state like LA, where annotations aren't included, would a lawyer purchase an annotated version from a 3rd party? I assume the information contained in the annotations is expected to be known, regardless of how it is obtained.
2. If a state elects to publish annotations as part of the only published code, does that lend any extra weight to the annotations (effectively, by putting them in the same book, and making that book the only copy of the state code, the state has signaled "these notes are the way we intend you to read/interpret/practice the law").
