Re: Are we running out of time?

Hi Arnaud,

could you outline a realistic time line for the remainder of the 
duration of the WG, i.e. proposed dates for the remaining stages of the 
publications? This would inform us to what we need to do to accomplish 
our goals, and which process changes are required if we still want to 
achieve them.

Thanks
Holger
