You said that we should use the current charter to start the WG.  I said that 
I thought that the current charter is not suitable to start the WG, and why I 
thought so.  You are now complaining that I should have produced a proposal 
for change.  However, according to you change was not an option.  So are you 
now saying that there is again the possibility of change to the charter?
