I forgot to put these on my earlier list.

9. Define whether headers such as Expires and Last-modified are to
modify a cache's state if they accompany a 304 response.  (There may
also be other responses for which this is a relevant question).

10.(a) Define what is supposed to happen when a cache receives a
request for a document in the cache after its Expires date, it
attempts to validate the document and receives a 304.
May or must the cached "expired" copy be served or should the proxy
return 404 (not found)?
(b) Define what is supposed to happen when a cache receives a request
for a document in the cache after its Expires date, it attempts to
validate the document and receives some error message (e.g. 404).  May
or must the cached copy be served or should the proxy forward
the error message it receives?
