I am having trouble figuring out what it is about the mail attribute  
that indicates "can not be blank".  I have a field that I need to  
create that has a good reason to be blank and am having serious  
problems figuring out how I would go about indicating that blank is  
acceptible.  I may just be missing it, but I can't find anything in  
the docs I've been looking at.
