Re: FW: @rel type 'describedby'

Dear Ms Cotton,

It has been a while since we received any communication from you 
concerning the proposed inclusion of 'describedby' in the Atom registry. 
I understand that there are a number of obvious potential reasons for 
this, the absence of an updated POWDER document in the public domain 
being the most obvious one.

We are in the very final stages of preparing for a transition request to 
Proposed Recommendation - it is only after that when the document that 
includes the describedby registration details will be formally published 
in space. For now it is available with W3C Member access at  
[1]. We also note the citation of this document (at its presumed future 
URI) and use of describedby in a recently published Internet Draft [2].

On behalf of the POWDER WG, I'd be grateful for any update you may be 
able to offer.

Thank you.
