Based on what I know, there are no single PID types. The PID is just mixed values which idividually, may have types. Maybe this is what you wanted:
Save Slot?
That doesn't have to do with making a pokemon legal.(Unless someone is reading the "journal" part of your bag and sees that it never says you got a pokemon that you have)
---------------------------------------------------------
Class?
Classes are a pokemon's ability. Depending on what ability you choose, you have to have a class to match it.

Trainer type in PPTE? (even though you said Pokesav Platinum)
Can't help you with PPTE.
If none of these values helped, this site might have what you're looking for:
