Syntactically speaking, neither “a farmer” nor “a donkey” can bind (in the sense of Chomsky 1986) an expression beyond the smallest clause in which they occur. In particular, neither can bind any of the pronouns in the main clause of [1a]. But the discourse referents associated with these indefinites, i.e., x and y, are in the accessible domain of [1b3], and therefore the anaphoric discourse referents in this embedded DRS can be linked to x and y. Put otherwise, they are bindable at a semantic but not at a syntactic level.
