SYNTAX: (minimalist theory) the requirement that substitution operations
in overt syntax always extend their target. This requirement is met iff the
designated position E for GT in overt syntax
is external to the phrase-marker K, i.e. extends K, unless E is an adjunct
position. In effect, GT can only insert material into the highest specifier
position of K*.
