Within the class of coordinators, MULTILEX foresees some features pertaining to the syntactic level, which in the Leech & Wilson proposal are collected under a unique feature Coord-Type:
Repetitive and correlative imply the specification of Expected Coordinator, i.e. `both' requires `and', etc., and the specification of Iteration, i.e. whether a coordinator can coordinate more than two conjuncts: ``and ...and ...and'' (more than two: yes); however, `but' (more than two: no). These last two attributes are introduced by MULTILEX only.
Sentence Introducer is used for coordinators which can introduce a sentence, linking it by coordination to the preceding sentence: ``And Mary left''. (`Either' cannot introduce a sentence in this way.)
In the EAGLES Proposal, these further distinctions concerning the Type of Coordination are treated as language-specific features.
