Ashok: thank you very much for posting this announcement. I found two nits, 
both of which I have fixed in place in the HTML:

* The document you checked in was still labeled as an Editor's draft, which 
seems inconsistent with the announcement. I've removed that text and it's 
now listed as a "Proposoed TAG Finding" (not a formal designation in the 
W3C or TAG process, but suggestive of the state of this draft I think)

*  The convention is that the "Latest version" is an undated link. I 
changed that, and also made sure that the version at [1] is the 30 Sept 
2011 version.

Also, the TAG resolution to publish [2] called for review until 15 
November. Specifically:

RESOLUTION: The TAG will publish the "Identifying Application State" 
document as a "proposed finding" by 30 Sept. 2011, and will solicit 
feedback to be due by 15 November. We will bring attention to the draft at 
TPAC and encourage people to send feedback. Unless major concerns are 
raised, goal is to publish a final finding no later than Jan. 2012 F2F.

I'm inclined to leave things as they are with a 28 October target on this 
draft, so that this round of comments will be available ahead of TPAC. We 
should indeed solicit more comments at TPAC, and hold off publication until 
those are available.

So, all set I think.

Thank you.
