+    \begin{block}{Non-traditional response}
+    A response that is not the single response
+    generated for a request received on the same transport.
+    \end{block}
+
+    \begin{itemize}
+        \item Define new versatile non-traditional responses
+        \item \textit{Define behavior of non-traditional responses in general}

+\begin{frame}{Behavior definition: OSCORE}\Large
+    \framesubtitle{New in -02}
+
+    \begin{itemize}
+        \item Explicit request or not: Request needs sender and sequence number.
+        \item Request nonce can only be used in one response.
+        \item If order matters, responses are ordered by sequence number.
+        \item If replaying matters, responses are subjected to the replay window.
+        \item If follow-up requests were made, transiently tolerate erroneous responses.
+    \end{itemize}
+
+    \bigskip
+
+    \ldots and that's it on the OSCORE side?
+\end{frame}
+
+\begin{frame}{Next steps}\Large
+    \begin{itemize}
+        \item Interop based on concrete documents adopting this?
+        \item Future in the WG?
