Benoit, All,

If fsFlowRecordTotalCountis equivalent to field #3, isn't 
fsPacketTotalCount equivalent to #2 and fsOctetTotalCount equivalent to #1 ?

Also, there is an issue with section 7 of this draft: it doesn't 
describe the semantics for any of the new IEs.
The word "Total" in the names seems to describe their function and not 
the semantic.
It's especially important to know whether these are absolute or delta 
counts.
