Hi Gonzalo and Benoit,

Please correct me if I am wrong, but my impression is that Benoit's
DISCUSS is related to the process of defining the  metrics in the
different places in the IETF in a consistent manner and keeping them in
one repository with a clear owner. Are there any text changes required
in draft-ietf-xrblock-rtcp-xr-pdv? 

Thanks and Regards,

Dan
