For constructions where the possessor pronoun is an affix on the possessum, I need there to be at minimum two sets of PNG features stored on the possessor+possessum form: the possessum’s PNG features, and the possessor’s PNG features. If the possessor pronoun affix does any agreeing with the possessum, then I need three sets of PNG features. Now, I’ve made a spot for agreement features at HEAD.POSS.POSS-AGR, but I’m having problems with the posessor’s PNG features getting mapped to the usual CONT.HOOK.INDEX.PNG path, which is where the possessum’s features should live. I’ve tried to remedy this by having the features map to the ARG0 of the pron_rel that the affix adds, but it turns out that ARG0 is of type
individual, while PNG is a feature of
ref-ind, so this doesn’t unify. Is there some way around this issue?
Here’s my pron_rel and some of the path to it, for reference:
LKEYS.ALTKEYREL #altkeyrel & noun-relation & [ PRED "pron_rel", LBL #lbl2, ARG0 #possessor & [ COG-ST activ-or-more, SPECI + ] ] ]
And then the attempt at putting features on ARG0 that didn’t work:
LKEYS.ALTKEYREL #altkeyrel & noun-relation &
[ PRED "pron_rel",
ARG0 ref-ind & #possessor &
[ PNG [ NUM sg,
PER 1st ],
SPECI + ] ] ] ].
