Concretely, how about the attached?  (I also got rid of a recently-added
extra comma.  While the compilers we use might not warn about that,
it seems unwise to assume that no user's compiler will.)

I guess one unresolved question is whether we want to mention these in
the SGML docs.  I vote "no", because it'll raise the maintenance cost
noticeably.  But I can see an argument on the other side.
