     * @remarks
     * The textual description in RFC 2986 (see https://datatracker.ietf.org/doc/rfc2986/)
     * indicates that a certification request contains "optionally a set of attributes".
     * The ASN.1 module in appendix A does not include the `OPTIONAL` keyword for this
     * component, which is a formal inconsistency. In practice, popular implementations
     * (for example OpenSSL) are tolerant and accept both forms:
     *  - the attributes field present as an empty context-specific element (A0 00),
     *  - the attributes field completely omitted.
     *
     * To be compatible with real-world CSR encodings, this property is marked
     * `optional: true` in the decorator. Consumers should therefore treat
     * `certificationRequestInfo.attributes` as possibly `undefined` and
     * handle that case (for example, treat `undefined` as an empty set of attributes).
