Your example "Pilot: FOXTROT VICTOR LIMA CHARLIE, AFFIRMATIVE." explains it all...this example from the AIM is actually incorrect ICAO phraseology. The correct ICAO readback is, of course, "Pilot: affirm, FOXTROT VICTOR LIMA CHARLIE".
Um, no, I don't think so.
ICAO is for read backs only to be ended with the call sign, as per 2.8.3.7.
the example wasn't a read back, so AIM is correct in that respect. There are plenty of examples of responses (other than read backs) in Doc.9432 that begin with the aircraft call sign.
Here's one: (4.5.5)
G-CD Are you ready for immediate departure
G-CD Affirm
However AFFIRMATIVE is not ICAO phraseology, it should just be AFFIRM. So in that sense, AIM doesn't match ICAO. For what it's worth.
