ATTi can only be blank when PTYPE is also blank, and means that all relevant entities will be included.  See comment 20 on the DRESP1 page.

**

ATTB = SUM – Response represents the sum of all ATTi entities.  See comment 21 on the DRESP1 page.

***

ATTB = COMB – Response is representative of all ATTi entities combined.

****

ATTB = G# – # is the number of the global ply defined on a PCOMPG.  See comment 13 on the DRESP1 page.
