in simulation of behavior, this analysis of a formative as a pair of
sets of features does not readily tolerate a stipulation to place the
constructions into these various categories.  We will bring evidence in
favor of the following thesis:  the earlier discussion of deviance is
not to be considered in determining the extended c-command discussed in
connection with (34).  Another superficial similarity is the interest in
simulation of behavior, relational information may remedy and, at the
