I came across a different use case of

        one OBR
        multiple identical OBX

where a "single test (protocol)" involves the patient bringing into the lab  3 
chemically-treated, self-sealing "cards" each of which contains a smudge of the 
person's feces (yes, that's "bowel movement") applied using a wooden applicator 
stick... yuk)

Anyway this is referred to as a test for "occult blood" and may be returned as

        OBR-Occult Blood

                OBX1-Occult Blood1
                OBX2-Occult Blood2
                OBX3-Occult Blood3

which would seem to make the case that each OBX be imported as its own row 
(could the subid be stored in GNUmed as a subfield within our test_reult fk?)
