Per the LEED Ref. Guide MR Overview Table 1, CSI Division 12 "may be included with Divisions 3-10, if done consistently for credits 3-7."

Does this mean we can selectively choose which Div. 12 items to include in all the MR credits (ex. include 123116 Mfr. Metal Sandwich Panel Casework but exclude 123623 Plastic Countertops) or does it mean that if we include any item from Div. 12 on the project then we have to include all Div. 12 materials?
