Are these parameters different from the ones in FetchRequest?

[Nate Chapin, 2013/09/06 19:34:03]

ResourceRequest and StoredCredentials exist on FetchRequest, the rest don't. I
could see the argument for using a FetchRequest, but there's also the fact that
a bunch of the stuff on FetchRequest isn't relevant in the sync case.
