How can I represent `array[object]` attributes?

[kyungmi]

I want to write document like below. But It doesn't seem to be processed with Apiary editor in appropriate way.

+ Response 200 (application/json)

    Using `group_by` option

    + Attributes
        + result (array[object])
            + `book_id` (string) - book ID that is grouping annotations
            + `annotations` (array[Annotation]) - annotations in this book
        + `total_count` (number)

How do I write this kind of structure?

I attach screenshot of the preview window of Apiary Editor.

You can't place key/value directory inside an array, you'd have to place it within an object as follows:

+ Response 200 (application/json)
    + Attributes
        + result (array[object])
            + (object)
                + `book_id` (string) - book ID that is grouping annotations
                + `annotations` (array[Annotation]) - annotations in this book
        + `total_count` (number)

## Data Structures
# Annotation (object)

+ some: thing
