I know I said I would like to move forward, but I realize that this change is 
something we need to get WG feedback/consensus on.

Lou/Kent, can I request a short WGLC (one week?) to make sure there are no 
concerns or objections to this change? That will also allow Joe to make the 
change in the tools.

Thanks
