The only use I can see for it is a *coincidental* match between groups of attributes in multiple tables. So is it worth complicating the mapping by introducing a concept with no analog in the DB world? My suspicion is that it will be very hard to explain to the users.
More on coincidental part. It will only occur in denormalized schemas, as DB "schema reuse" is done via normalization. So it is an edge case.
