-- quantifier and an optional numeral can be discerned.

-- Whether the resulting determiner is singular or plural depends on the
-- cardinal.

-- All parts of the determiner can be empty, except $Quant$, which is
-- the "kernel" of a determiner. It is, however, the $Num$ that determines
-- the inherent number.
