Quantifiers of elided nouns are annotated under NP. In such cases, since noun elision is not represented in the annotation system, the quantified NP is composed exclusively by the quantifier (or by the quantifier and a determiner).

Notice that quantified subjects with empty heads should be annotated as (NP-SBJ (Q)) (and not as null subjects plus floating quantifiers).
