Hi Rinke,

Thanks for this. Luckily, QRG isn't going to LC in this round, so we  
will have plenty of time to sort out these issues. I suggest that, to  
make things easier for the people working on producing the documents  
for this round, for the time being we restrict changes to those that  
are absolutely necessary.

Thanks,
Ian
