In the docudemon_conditions.txt there is this condition:

Identifier: OnAWarFooting
Trigger requirements: faction
Parameters: None
Sample use: OnAWarFooting
Description: Is the faction on a war footing?
Battle or Strat: Strat
Class: ON_A_WAR_FOOTING
Implemented: Yes
Author: Guy

I was just wondering three things:

1. Does it work?
2. What does it do?
3. Could you please provide an example if it does work?

Thanks.
