A mailing list for the OSI is probably appropriate. I think written 
documentation is a good goal, but realistically, it's easier (and 
perhaps better) just to say that the expected behavior for an interface 
is simply that it pass the unit test. If we design and comment the unit 
test carefully, then any deviations from the required behavior will be 
easy to understand and fix. This way, we don't have to try to keep the 
documentation in sync with the unit test if we make changes. What do you 
think?

Cheers,

Ted
