A plural phrase that explicitly selects all of matching objects. For English, this would be a phrase like "all of the marbles". This type of phrase matches all of the objects that match the name in the plural, except that if we have a collective object and we also have objects that are part of the collective (such as a bag of marbles and some individual marbles), we'll omit the collective, and match only the individual items.

Grammar rule instantiations in language modules should set property np_ to the plural phrase match tree.
