    # with UNIMARC Koha instances does *not* include a subfield $o for fields
    # 200 (Authorized Access Point - Personal Name),
    # 210 (Authorized Access Point - Corporate Body Name), and
    # 220 (Authorized Access Point - Family Name).
    # This is per the official IFLA Manual, and effectively means we can save
    # the ISNI number in the @subfield_loop array without worrying about
    # overwriting any previous value that may exist.

    # For more information, see the official IFLA UNIMARC Authorities Format
    # Manual (online ed., 1.0.0, 2023), pp. 350, 363, 385.
