Student as PIC in IMC?

I'll be taking my checkride in a few weeks and one of my goals has been
to have at least 10 hours of actual IMC before I take the ride. It's
going well; I'm at 9.1 and only 2 of those were just boring a hole in
clouds on a cross country.

I have been under the impression that I could log PIC time when under
the hood but not in actual IMC, because I am not rated. Last night,
however, I read something in the ASA oral test prep book that seemed to
imply that this was not the case.

So, assembled wizards, should I be logging PIC time in IMC? or not?
