 \subsection{Tip Contents}
 
+xxx up to here

+We need worry only about $C \in \py$.  
+And $\patchof{C} = \patchof{L}$
+so $L \in \py$ so $L \haspatch \p$.  We will use the coherence and
+patch inclusion of $C$ as just proved.
+
+Firstly we prove $C \haspatch \p$: If $R \in \py$, this is true by
+coherence/inclusion $C \haspatch \p$.  If $R \not\in \py$ then
+by Tip Merge

 We will consider some $D$ and prove the Exclusive Tip Contents form.
-We use the Coherence of $C$ as just proved.

+
+So by definition of
+$\haspatch$, $D \isin C \equiv D \le C$.  OK.
