Oops!  I meant to add that Sean's assessment matches mine, I think:    (01)

> A data model assumes a set of entities, and the choice of which entity

That is exactly the distinction I make in Rule 2.    (03)

And this is a more erudite/polite formulation of my Rule 1 -- that the 
ideas are now (accidentally, ignorantly, or deliberately) conflated.    (05)
