Hello Karim,
I have no problem with the words in your note, but then you have to rename the draft to be "IPv6-over-nearterm-3G", or better, "IPv6-over-3GPPr5-PDP". That gets the point across. If it's "IPv6-over-cellular", then you have to write the specification to apply to ALL cellular systems, current and future. That was the point in my note you quoted. Regards, Charlie P.
