The table in [`.attr( attributeName )`](https://api.jquery.com/attr/#attr1) will need a new row for 4.0+, and [`.attr( attributeName, value )`](https://api.jquery.com/attr/#attr2) will need updates to document the acceptability of a `false` value and...

> I don't know what "and id is valid as the first argument to GetNamedTimeZoneEpochNanoseconds and GetNamedTimeZoneOffsetNanoseconds" means since those operations do not have any assertions or return completion records,...

I've raised the concept of "iteration hazard" [elsewhere](https://github.com/unicode-org/message-format-wg/issues/507#issuecomment-1787685799), and reiterated it in #526 as stemming from a fundamental distinction between "simple message" vs. "complex message" rather than the former being...

@JHawkley there is no need for `break with …` anywhere AFAICT, because blocks in which `break` is semantically relevant all appear to use UpdateEmpty to reach behind it for their...

Observable changes are sufficiently rare that I think the default should be to document them, with exclusion requiring specific justification.
