Oh, interesting. When you put it that way---"Example item" and "Continuation ..." being the same semantic unit---I see the problem. And why nesting is easier to implement when the semantics are based on lines.
I think it's also interesting the way you say "The “Another Sub-Sub Item” should not be allowed". Seems to me the format and tooling should do what the user wants and expects, or at least try to. Why not allow it if the user wants it that way?
