Re: W3C Content Transformation Guidelines - Last Call - comments welcome ( LC-2005 LC-2006 LC-2007 LC-2004)

Dear Ed,

The Last Call review period for the Guidelines for Web Content 
Transformation Proxies is over and we have not yet heard from you. We 
were wondering whether you had time to review the response to your 
comments below and the updated document, and whether you could let us 
know if you agree with it or not via email.

The header of the previous email was generated from a template that did 
not give us the opportunity to apologize for the time it took us to get 
back to you. Comments received during the first Last Call review period 
generated a lot of discussions within the group. Resolutions of the 
issues took more time than expected. The group thinks the document has 
quite improved as a consequence, apologizes for the delay and would like 
to thank you again for your contribution!

Thanks,

For the Mobile Web Best Practices Working Group,
Francois Daoust,
W3C Staff Contact.
