... zich6.1
In such a case, Dutch has to use an inherently reflexive predicate (Reinhart & Reuland 1993). When a normal transitive verb is used, Dutch has to insert a SELF-anaphor such as zichzelf. These cases are irrelevant to the topic of this paper.

The exact workings of the rules here are irrelevant: I am not sure whether it would really be Rule 1 applying here, since we do not even get to the stage where the Interface is considered. Let us simply assume for the moment that either one of the rules (or in more general terms, Economy) prevents costlier options including discourse from being used.

...Jan 6.5
The status of the Number feature is completely different from that of Gender, Person or Category. Different occurrences of Number in one and the same numeration can make independent contributions to interpretation, as becomes clear from (5):

(5) The times where rough, men were fighting men (and women where fighting women)

Thus the Number feature can not be deleted even though Jan has in principle the same Number feature, since deletion would violate PRD.
