Procedure; Human Factors; Chart Or Publication
Flight operating on an ICAO descent via clearance; ATC issued a new altitude to descend to but did not specifically cancel star altitude constraints. Confused with the differences between the FAA and ICAO descend via clearance requirements (FAA needs to re-issue descent via for constraints to be in effect; ICAO does not) we descended below the star constraints. Additionally; later on the flight; during approach; the pilot flying failed to operate below the speed limits [160] established for Mexico's airspace and for the Runway 5R ILS approach.
Air Carrier First Officer reports confusion descending into MMMX over RNAV descent criteria for ICAO vs. FAA. The 160 KT speed restriction on the ILS 5R approach is also overlooked.
