Sailesh,
I’m not sure what to record. David had indicated that this is broader than the requirements for 4.1.2, and in fact the first exception states "There is a programmatically determined relationship between the new content and the control that triggers it;” which pretty much means that if you have a form control with a validation message that comes up when the control is in an error state and that is programmatically associated with the control then that new content doesn’t need to meet 3.2.7.

3.2.1 and 3.2.2 are about changes of context. That may or may not be related to new content on the page. 

I think that these issues have been discussed and as a result I didn’t think that there was an objection. If I misinterpreted and there is an objection, please clarify what the specific objection is.

Thanks,
AWK
