Completeness and Coherence  (Subcategorization)
  These well-formedness conditions are not implemented in the
  grammar.  So it will be possible to build f-structures for sentences
  with subcategorization violations.  After the f-structure is built,
  the sentences will fail because of a violation of Completeness
  (missing an argument) or Coherence (extra argument).
