[RDA-L] RDA Authority Records -- See From

Hi all, I've been noticing a $wn in the see-from fields in RDA authority records, and I'm not sure what the rest of the codes mean (nea, nna, etc..) I've found the explanation of what the subfield means, but I can't seem to find a list of what the codes in the subfield mean. Could anyone

What you're most likely to see are: $w nne [used for former established heading; valid code in both AACR2 and RDA] $w nna [used for pre-AACR2 heading that is valid as an AACR2 reference] $w nnaa [used for pre-AACR2 heading not valid as an AACR2 reference, so shouldn't be displayed] $w
