[GS] In principle I agree with you. For the sake of graphical continuity, I'll need to get creative so that I don't need to represent the logical structure of the SIP CLF record as: <IndexPointers> <MandatoryFields> <OptionalFields> 0x0A I'll kick it around in my head as to how best represent that.
