     * sublocality (town or village). These components have dedicated fields in the
     * `Address` object because software sometimes behaves differently based on them.
     * For example, sales tax software may charge different amounts of sales tax
     * based on the postal code, and some software is only available in
     * certain states due to compliance reasons.
     *
     * For the remaining address components, the `Address` type provides the
     * `address_line_1` and `address_line_2` fields for free-form data entry.
     * These fields are free-form because the remaining address components have
     * too many variations around the world and typical software does not parse
     * these components. These fields enable users to enter anything they want.
     *
     * Note that, in the current implementation, all other `Address` type fields are blank.
