Determiner Conjunction

In determiner coordination, all of the determiner feature values are taken from the left determiner, and the only requirement is that the <wh> feature is the same, while the other features, such as <card>, are unconstrained. For example, which and what and all but one are both acceptable determiner conjunctions, but which and all is not.
