Interesting. If that's the case, then the documentation for that method is correct, the caller is responsible for freeing the returned object. I will file a bug report.
Thanks.

However, when I run my code through the analyzer in Xcode, it says the serviceResult is released too many times, which would imply that it is already autoreleased. I Googled this and found several examples where it was not being released. If I comment-out the release code, the analyzer does not complain.
That's because it's missing a CF_RETURNS_RETAINED in the header for that method, which the analyzer needs to know what's going on. I'm not sure there's any way around this other than filing a bug and hoping Apple updates the headers in the next release.
(Another example of this is SecTransformExecute in Securty.framework)
