This is excellent, Steve. Thank you very much. I:

* Added your verbiage to both the beginning of "How an incomplete
Attribute Can Help Improve the Web" and to the "Details" section of
the proposal. [2]
* Incorporated part your verbiage [3] into to an alert for a proposed
audience based validator user interface [4].

What do you think?
