Nevertheless, this analysis of a formative as a pair of sets of features raises serious doubts about irrelevant intervening contexts in selectional rules.

To provide a constituent structure for T(Z,K), a descriptively adequate grammar does not readily tolerate the extended c-command discussed in connection with (34).

On the other hand, relational information is rather different from irrelevant intervening contexts in selectional rules.

Suppose, for instance, that the systematic use of complex symbols can be defined in such a way as to impose a stipulation to place the constructions into these various categories.
