Separate Changing and Shower Rooms

I would like to clarify the LEED V2009 requirement for Showers and Changing Rooms. Question: Does LEED stipulate at all to provide a separate changing room from the shower compartment? Background. We have two staff toilets (one for male and one for female). We added a shower compartment (fully enclosed)-- with a shower base and a dry area which totals to almost two meters in length. Fixtures such as hooks are provided to hang towels and/or clothes. I was told that I should still provide a closet to classify the whole space (where the toilet and sink are) as a changing area. I am challenging that because I believe the closet is unnecessary and that the Shower compartment is enough for the LEED intent. Can anyone please help me? Can someone clarify/confirm this or point me to a document whether the separation is necessary? Thank you!
