Demountable Partitions - Walls or Furniture or neither?

There was a credit interpretation about demountable partitions (EQc3.2, 12/1/07) that states, "Full height, demountable modular walls are essentially the same in form and function as permanent wals and as such are not considered funiture...Please note that such modular walls potentially affect other LEED credits (such as daylighting and views) and should therefore be included in any calculations and submissions required for those credits as well." Caveats? Twofold - first this was a NC CIR, so I am not sure how it applies to CI. Secondly, USGBC has indicated that they are not bound by LEED v2 CIRs in LEED v3.
