Hi Abe,

Thanks for your comments. I'm happy to put column* into both.

Could you please suggest what the semantics of mapping a single field  
to multiple columns means? Are you thinking of a multi-column foreign  
key usage for references (relationships) or do you see it applying to  
primitive values as well?

Thanks,

Craig
