For example Chuq jí máq máq should be outright rejected, as chuq is not ditransitive. Right now it draws a tree with v in it.
I think there are also "minimum arities", and that sentences like Tua dua jí are really short for Tua dua jí sa sa or something, and this should be reflected in the tree instead of drawing some kind of strange tree with nullary dua. But I have to check with @solpahi on this.
