Tom, I support the "e-mail" conclusion in favor of changing STATE when the
CANCEL or ABORT is completed and associated attributes (ex. sheets used)
are at their final value.

This has been discussed openly for a significant duration on JMP,
so I feel agreement has been reached there (unless someone objects).
Yes, we do need better IPP coverage of this topic.

You are correct ...

I would see this as a late change and overly complex, at this point.
