A single share acquisition during the income year, for the underskjema's KjopArvGaveStiftelseNyemisjonMv (Transaksjoner) block.
ervervstype is the RF-1086 acquisition code. Only "N" (stiftelse/nyemisjon
m.v.) is verified against Skatteetaten's published example payload; codes for
kjøp/arv/gave are not authoritatively documented (the XSD field is free
text), so callers must not emit unverified codes into a real filing.
