predicative noun
negation
verb (xpred=...). 3 . This information (e.g. pform, type and num) cannot be
coded directly as an extended head feature of the noun since the predicative
properties can be delegated to a dependent relative pronoun, in whichcasethese
constraints apply to the relative pronoun and not to the predicative noun itself
(e.g. He was proud of the decision which his daughter had made). The value
of vsup are head features and the value of xpred are extended head features.
The aspectual structure of the noun is unied with that of the SV, by way of
which the semantic tense and aspect are shared between the predicative noun
and the SV. In addition, the SV and the predicative noun share information
about the scope of negation.

The result of the subcategorization of the predicative noun by the SV is represented
in the following structure, where the argument slot for the subject is
still accessible.

In the treatment implemented in CAT2 the predicative noun selects the SV together
with the aktionsart this verb is associated with. [Krenn and Erbach94](pg.389) suggest
the SV select the predicative noun and have a xed aktionsart. This approach, however, is
not only intractable for generation where the predicative noun somehow has to generate its
SV, but implies that everySVhasalistofhundreds of lexemes of predicative nouns it may
select and third, that multiple entries become necessary if the same SV is used for dierent
aktionsarten (cf. (179)).
