Thanks for your reply!
I know what you mean now, NAME_RCID can tell the difference between Feature
records' RCID and Spatial Records', and it is easily to know the NAME_RCNM
subfield is from Spatial Record from its prefix-"NAME".

I always called this field NAME_RCNM so it isn't about what edition it is
from. I believe it is named this because it is the RCNM extracted from
the NAME field of the feature (FSPT). I presume it is used to lookup
the RCNM and RCID in the set of spatial records when composing the geometry
for the feature.
