Currently for nouns in the Lexicon, parent’s choice for determiner is only considered by the validation code if it is “impossible” or “obligatory” (but not “optional”).
As a result, I get a validation error when I am trying to have my nouns inherit the “optional” constraint from a parent.
Is that intended? Is there something wrong with trying to inherit “optional determiner”? If so, I could change the validation message or something. If not, I can fix the validation code, but it seems unlikely that nobody has encountered this before.
