Lighting Controls in Multi-occupant Spaces

I'm confused about the credit requirements. Reviewer comment: Per the Calculations section of IEQc2.2 in the LEED Reference Guide, provide a narrative to describe the lighting controls in the conference room and ensure that the space allows for more than two levels of lighting. LEED Reference Guide: No specific types or numbers of controls are required. I can not find anywhere in the LEED addendum, reference guide, etc that lists requirements for more than two levels of lighting. But I found that exact statement in an online pdf from the GBCI: LEED Project Submittal Tips: EBOM 2009. Which standard should I be using, the LEED Reference Guide or the pdf from GBCI. Or is there a source of LEED changes that I'm missing.
