(2) a conceptual row must contain at least one columnar object which is
not an auxiliary object. In the event that all of a conceptual
row's columnar objects are also specified in its INDEX clause, then
one of them must be accessible, e.g., have a MAX-ACCESS clause of
"read-only". (Note that this situation does not arise for a
conceptual row allowing create access, since such a row will have a
status column which will not be an auxiliary object.)
So this makes it clearer that a table that has only auxiliary objects of
which one of them has a MAX-ACCESS of accessible-for-notify or read-only.
