 ## client_certificate_type and server_certificate_type extensions
 
-The TLS extensions ``client_certificate_type`` and ``server_certificate_type`` defined in {{RFC7250}} are used to negotiate the type of ``Certificate`` messages used in TLS to authenticate the server and, optionally, the client. This section defines a new certificate type, called ``VC``, for the TLS 1.3 handshake. The updated ``CertificateType`` enumeration, the corresponding addition to the ``CertificateEntry`` structure, and the ``Certificate`` message structure are shown below.
-In the current version of the document ``VC`` certificate type is set to 224, one of the values indicated by IANA for private use. ``CertificateType`` values are sent in the ``server_certificate_type`` and ``client_certificate_type`` extensions, and the ``CertificateEntry`` structures are included in the certificate chain sent in the ``Certificate`` message.
