They are there for future expansion, but I don't know exactly what they were added
for.

If you look at the gda.idl file:

union FieldValue switch (boolean) {
 case FALSE:
  Value v;
 };

So, the _d field is the one used internally to determine if there is a value or
not (FALSE, TRUE). It is like the _d member in the GDA_Value struct.
