Ok, thanks very much. So what if the server just rebases the edit, and that results in the caption being set a second time? ie most recent wins. Don’t see how

Ok, thanks very much. So what if the server just rebases the edit, and that results in the caption being set a second time? ie most recent wins. Don’t see how this would break a schema? Encoding “adding a caption” as “add an additional child called caption” would be silly, as we know there can only be one caption. So the op would be “set the caption”.
