 This part of the proposal introduces changes made to existing TLS credential APIs. Changes include:
 1. Replacing all the occurrence of "*_server_authorization_*" to "*_authorization_"
 2. Removing `grpc_tls_key_materials_config`, `grpc_tls_credential_reload_config` and `grpc_tls_credential_reload_arg` 
-3. Adding API `grpc_tls_credentials_options_set_certificate_provider`, `grpc_ssl_server_credentials_set_min_tls_version` and `grpc_ssl_server_credentials_set_max_tls_version`
+3. Adding API `grpc_tls_credentials_options_set_certificate_provider`, `grpc_tls_server_credentials_set_min_tls_version` and `grpc_tls_server_credentials_set_max_tls_version`
+4. Adding API `grpc_tls_credentials_options_set_root_cert_name` and `grpc_tls_credentials_options_set_identity_cert_name`
 
 Here is how the API would look like after these changes. For simplicity, all the comments are omitted.
