Timeout strings

i have been working on some idea where 1 buff goes over into another after it expires, like hunger, bladder and pregnancy.

all of them have a timeout string at the end of the data.

like this for the 'has to pee'buff

<T n="timeout_string">0x3D6BCEB3<!--Becomes {1.String} in: {0.Timespan}--></T>

hungry has the exact same line and string code

i want to know where i can find what these strings do, and where the reference is for that {1.string}

so i can use it to make the Buff1 go over into Buff2 and then maybe death
