--- Comment #13 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-12-16 20:16:16 UTC --- Up to Jon to decide which details he wants to add to the docs, but please always keep in mind that in the areas where the behavior isn't implementation defined only the ISO Standard (possibly amended per DRs) is the ultimate reference.
