I'm referring specifically to your claim that the existing specifications can result in a doubling of CE marks in the reassembled and decapsulated packets, relative to the number present in the encapsulated, fragmented packets arriving at the decapsulator.  I cannot at present identify any mechanism which permits this to occur, but it seems to form the basis of your justification for modified language.

So *one* of us has clearly misread the specs in question.  I just want to figure out which of us it is.  You could do so by quoting chapter and verse for such a mechanism, and we can work from there.
