/**
 * This file contains classes to handle non-standard key descriptions and authorizations.
 *
 * Due to an issue with the asn1-schema library, referenced at https://github.com/PeculiarVentures/asn1-schema/issues/98#issuecomment-1764345351,
 * the standard key description does not allow for a non-strict order of fields in the `softwareEnforced` and `teeEnforced` attributes.
 *
 * To address this and provide greater flexibility, the `NonStandardKeyDescription` and
 * `NonStandardAuthorizationList` classes were created, allowing for the use of non-standard authorizations and a flexible field order.
 *
 * The purpose of these modifications is to ensure compatibility with specific requirements and standards, as well as to offer
 * more convenient tools for working with key descriptions and authorizations.
 *
 * Please refer to the documentation and class comments before using or modifying them.
