Save file format: what is "type" field of "time_duration"?

For example (1.33):

        temporary_liberty_desire={
            timed_modifier="demanded_additional_tribute"
            time_duration={
                {
                    type=195
                    value=17.547
                }
 
            }
        }

I'm interested where type=195 is coming from. It's definitely not a numeric equivalent of "demanded_additional_tribute", as "demanded_artifacts" and "enforced_religion_different_group" also have type=195, however there are modifiers with type 196.

Seems like all modifiers that increase LD have type=195 and all that decrease have 196, so they are basically plus and minus signs. In 1.34 they are changed respectively to type=201 and type=202. Weirdest representation of integer number signs that I've ever seen.
