What about the rest of the attributes if the object contains a mismatched
guarded field? Will they be updated, or will the whole object be rejected
(I assume the latter). I assume the answer to this question will be
evident when I produce the first "guarded-reject" update, but it would be
nice to have this stated clearly in the text as well.
I have no other comments -- this looks good as far as I can see.
