No, it's documented to be introduced in 10.5, while the alternative
IOPMAssertionCreate is already deprecated on 10.6. So if I believe the 10.6
docs, I should use IOPMAssertionCreateWithName and not IOPMAssertionCreate,
both on 10.5 and 10.6. And all the engineer said is that it's not documented
AFAICS. Filed a bug report.
