DESCRIPTION         top

       This function will register a new supplemental data type (rfc4680).
       The registered supplemental functions will be used for that specific
       session. The provided  type must be an unassigned type in

       If the type is already registered or handled by GnuTLS internally
       GNUTLS_E_ALREADY_REGISTERED will be returned.

       As supplemental data are not defined under TLS 1.3, this function
       will disable TLS 1.3 support for the given session.

RETURNS         top

       GNUTLS_E_SUCCESS on success, otherwise a negative error code.
