+ * \brief Begin TLS 1.3 key schedule by calculating early secret.
  *
  *        The TLS 1.3 key schedule can be viewed as a simple state machine
  *        with states Initial -> Early -> Handshake -> Application, and
  *        this function represents the Initial -> Early transition.
  *
- *        In the early stage, mbedtls_ssl_tls1_3_generate_early_data_keys()
- *        can be used to derive the 0-RTT traffic keys.
- *
  * \param ssl  The SSL context to operate on.
  *
  * \returns    \c 0 on success.
