For an example, let us return to the case of non-peripheral extraction ‘(what) Mary put — there’.  Assume we have two modes of composition: ⊗c and ⊗d.  Regular valency requirements are expressed in terms of the slashes for the ⊗c product.  Discontinuous dependencies are handled by structural postulates of mixed associativity and commutativity, and an inclusion postulate expressing the relative ‘strength’ of ⊗c and ⊗d. The type-assignment to the pronoun ‘what’ provides access to these postulates, so that it can establish a link with a non-subject np hypothesis, also in a sentence-internal position.
