Assume an April [1] meeting with universal support.  The AC recommends 
it for last call, ten working days.  Now it's mid-May, and the AC
meets again and decides that there's been nothing but support in
last call, and forwards to the Board.  The Board agrees, and 
ratifies the policy.  It's probably June by now, six months from
the date of the proposal.

Does this need to be a Global Policy?

Existing data fields will have to be changed.  Code changes and
template changes are required.  This may be significant; I'm sure
staff will advise at the public policy meeting.

I agree, and appreciate your work on this.
