I think that C15-0.0.1.13 (IBA 1.2 p.896) results in the second
possibility above as it states:

C15-0.1.13: SA shall reject as invalid any attempt to create, modify, or
delete a ServiceRecord in which the ServiceP_Key is not present in the
P_Key Tables of both the port identified by the ServiceGID and the port
from which the request came. 

So that is more stringent and the ServiceGID must be a (valid) GID in
the subnet.

I believe the test ais ttempting to create the SR with an invalid
ServiceGID as its subnet prefix is 0. It should be rejected by the SA
per the rule above.
