(By Jakob Lesage): "Morphological case involves any type of case marking (or flagging) that is phonologically bound (affixes, clitics, tone, alternation, vowel lengthening, etc.). Core arguments are those having S, A or P function. If a bound marker distinguishes S from non-S NPs, this counts for a 1 code. Optional marking and marking with portmanteau morphemes (e.g. a marker both indicates that a noun phrase is plural and that it has P function) also count."
