| NULL is the unknown value. Your dates are unknown. Sounds like a  
| perfect match to me. I'd be interested in hearing the other point of

| view.

This may just represent fuzzy thinking on my part, but...

I can see where I would be interested in the difference between 
as-yet-unknown (will be filled in during one of the next rounds 
of data entry) and unknowable (won't ever be filled in, barring 
paradigm shift or policy change).


Or is this standard question nr 27, and did I just flunk?
