Re: ODM document -- n-ary relations

Thanks, Elisa. I'll try to look at the other sections, but can't

On the n-ary part however, some clarification would be appreciated. 
I've since had some communication with Evan and I think he has concerns 
about that that part as well. Perhaps, a quick discussion at the 
tomorrow's telecon would be worthwhile.
