The flag indicating whether a NP has a negated determiner is now encapsulated in the algebraic parameter Agr, removing the extra field in the NP linearization type.
Agreement with the focus part (the object) works not only for Pers3, but also for Pers1 and Pers2 NPs (if the verb requires non-typical subject/object valences).
Object-dependent double negation works (in addition to the subject-dependent double negation).
The first one is motivated by PhrasebookLav, the second one - by AttemptoLav.
Also a couple of minor fixes.
Double negation: sebject-dependent - works, object-dependent - still has to be fixed (in VerbsLav).
Structural words: everybody, somebody, nobody.
Both motivated by AttemptoLav.
The case of the topic part of a clause (~subject) can now depend on the verb, allowing for less frequent agreement.
E.g. "man[Dat] garšo pica[Nom]" ("I like pizza").
The default case for the topic/subject remains the nominative case.
