where do i find the achievements associated with player commendations?

i am on PS3. and have been through the achievements display several times now. and can't find nothing.


it says, "These commendations can be accumulated over time, and by receiving a certain amount, you will unlock achievements that grant special rewards.".

maybe we have to get a certain amount before the achievements will actually show. or maybe Square Enix has forgotten to add them. lol :/


anyone?
