Ok, so the new Rule 3 is in effect saying that if the child of the repeated middle group is repeated, then because 1-level and LIST/MAP annotated schemas cannot mix, the middle group cannot be the type so the child is the type. The side consequence of this is that the middle group has to have a `LIST` or `MAP` annotation to allow the 3rd level to be `repeated`. So is it true then that the `repeated` keyword may only be used for the child of a `LIST` or `MAP` annotated field when those annotations are in use? And if that's true, then a 2-level structure cannot be `repeated` as stated above? ``` In contrast to 3-level structure, the repetition of 2-level structure can be `optional`, `required`, or `repeated`. ``` -- This is an automated message from the Apache Git Service.
