det:numgov: pronominal quantifier governing the case of the noun
Pronominal quantifiers are labeled det:numgov instead of det
because they normally do not agree with the quantified noun in case
(unlike non-quantifying determiners).
The quantifier requires the counted noun to be in its genitive form. The whole phrase (quantifier + noun) is treated as a singular neuter noun phrase and it can fill roles where nominative, accusative or vocative noun phrases are expected.
In UD the quantifier depends on the quantified noun and the det:numgov label is used to preserve
the information about case conditions.
