It is not documented.
In the Netherlands we have at present 35 concessions for buses [1]. 
These concessions will change operators regularly (they range in 
duration from 10 to 20 years, so on average every year 2 concessions 
will end) and a new operator has new ideas, new lines, etc. Also 
sometimes concessions get split or combined.
Making a relation for each concession greatly improves maintainability. 
You only have to load one relation in JOSM to get all lines and work 
from there.
I would be really cross if someone decides to delete those relations :P

That's not how I do it. But again: I'm not saying I'm doing it 100% 
correctly.
