While I think it is fine to be tuning the language of these definition, the key point, as I mentioned in an earlier message, is that these definitions are not really normative with regard to such behavior.  There are other normative portions of the specification that define precisely when and how [[Getter]] and [[Setter]] are used.

Also, we have plenty of time over the next couple months to fine tune this sort of language.  In preparations for next week meeting it is probably most important to put time into identifying where there are real unresolved technical decisions that need to be finalized. Tweaking the wording the reflect the intent of those decisions can follow after the meeting.
