Question on League Mods

Hi, I've downloaded the Pro Real World Mod lately and if you don't mind, have a few questions:
The teams.xml that comes with this - I'm not sure what the use of it is. It has many league formats. Includes an "NFL 2002 to Present" format that is not available for selection in the game menu. I notice the schedule csv file only has 16 games per team. Will it not work if we select Modern Day 17 games format? "Modern Day' formats also aren't in teams XML file. Anyway I tried
I got an "An error has occurred" when trying to use that schedule in Modern 16 game and Modern 17 game. Where in league setup would we use Teams.XML, for instance the actual team names and logos, how does the game know where to look for them?
Speaking of which in schedule how do you know what Team ID goes with each team?
I know these are lots of questions but I really love this game so far and wish I could figure out the setup a little better.
