=head1 NOTES
+These functions are similar to L<SSL_CTX_set0_CA_list(3)> and similar functions
+but only have an effect on the server side. These functions are present for
+backwards compatibility. L<SSL_CTX_set0_CA_list(3)> and similar functions should
+be used in preference.
+
When a TLS/SSL server requests a client certificate (see
B<SSL_CTX_set_verify(3)>), it sends a list of CAs, for which
it will accept certificates, to the client.
