I couldn't find any documentation on del(), but as a
wild guess I tried:

(C1) U: 'diff(U,S)*S + 'diff(U,V)*V;
dU dU
(D1) -- V + S --
dV dS
(C2) diff(U);
dU dU
(D2) -- DEL(V) + -- DEL(S)
dV dS

which seems OK.

    Any suggestions on what to say?

    I was going to say something like:

    DEL(var) is the differential of var. So DIFF(F(X)) is
    DIFF(F(X),X)*DEL(X).

    Maybe add a couple of examples as well.

    How about that?

    I really don't have any suggestions. Yours seem reasonable -
    certainly a start. Examples are always good.
