I'm not sure if I'm going to explain it right or not, but from my understanding, they're used to reference the Armor Database - or rather, the stats of the armor piece from a separate page. The parameter is used to state what type of defence stat the template has to look up, whilst the  states what grade the value must be drawn from.
