Thanks Martin for pointing out this: I had briefly considered this 
"difficulty"
in the resolution, but unfortunately got distracted by other issues and 
couldn't
really spell it out.

Personally, I agree, but don't know which is the correct procedure in 
such cases,
that is when the DR is in the WP status?!? Is it still possible for the 
committee
to change the resolution or another DR must be opened??

Thanks,
Paolo.
