Re: comments on DUV and some proposals

Joao Paulo,

Thank you for your comments,  as you are aware this is our first draft.
Unfortunately given the timing we will not have time to review and respond
to your thorough comments prior to the meeting.

Having said this, the editor team still feels the need to collect and
review all additional comments from the team and public.

Cheers,

Eric  S
