Maya render passes overview

I've been trying to render out passes in maya and come across this on Gnomon. It's more of a brief overview of each one (i.e doesn't tell you how to construct those passes) but may be useful - should be able to figure some of them out as well based on those descriptions.

btw, i've run into a problem with maya 2009 - if you use any maya material X, they don't render out properly in the new auto-pass feature. There is a solution - you can go to the material attributes and scroll down to where it says 'upgrade' shader, inside the tab there's an option to convert the shader to the 'passes' version which is compatibe with render passes. Even still there are other bugs in render passes (some x-passes materials only support certain render passes for example)...
