XCR Editing and Factions

Hi,

I was tinkering around with the XCR File of the original Campaign to learn a bit about the structure and function.
So I was wondering if it is possible to assign factions to a side in the MAP_xxx files. I tried around with some guesses, but nothing works.
So I looked up some other XCR files, and found 'faction="x"' in the Holkuk Chapter. That was one of my guesses, so it didn't work.
It also looks like it doesn't work in the Holkuk Chapter either.
Am I doing something wrong or missing something?
Or is it not yet implemented to function or a bug?

Many thanks and Cheers!  

Faction-assignment hasn't been implemented in 0.8.9b. It's only available in the unreleased 0.9.0 version (and in future, all versions which follow).
