In Maya 7, they took it out of the render globals but they didn't update the docs. It messed me up the first time as well. Now what you have to do is create a render layer, right click on the new render layer and select Attributes. Then in the attributes window scroll down to Render Pass Options.

Maybe Autodesk will do a better job of letting us know when they overhaul a major feature than Alias used to. I hope this helps.
