The Problem They Think They Are Giving You

The problem they think they are giving you: We would like to add a new format for retrieving this data to the existing one.

The problem they are actually giving you: You need to go figure out how a half-dozen-year-old code flow handles the existing extraction of said data, using documentation that is outdated due to code accretion in the intervening years.  Once you have a handle on that, you have to modify it so it does not rely on the old assumptions, determines which potential version of the data it is looking at every time it attempts to retrieve a value, and then... what was it again?  Oh yeah, add a new format for retrieving the data.
