 I added the feature [ QUES bool ] to the "verb" type. This bool
 feature is + for interrogative clauses, and - for non-interrogative
 clauses. In the lexicon, each verb has two entries: the ordinary verb
 entry is [ QUES - ], and the verb-neg-verb entry is [ QUES + ].

As reduplication counts as hard morphophonology :-)

 1. The "matrix-interrogative-clause" type requires its daughter to be
 an S (fully saturated verb) that is a main clause [ MC + ] with an
 interrogative verb [ QUES + ]. The mother S will also be [ MC + ]. (In
 "rules.tdl", I declared "matrix-interrogative" as an instance of this
 type.)

 2. The "embedded-interrogative-clause" type requires its daughter to
 be an S (fully saturated verb) that is not a main clause [ MC - ] but
 has an interrogative verb [ QUES + ]. The mother S will also be [ MC -
 ]. (In "rules.tdl", I declared "embedded-interrogative" as an instance
 of this type.)

If the only difference between these is their MC value, why bother?

 (Slight differences in handle numbers: I don't think this is
 important. The top-level event "u2" vs. "e2" is different: How
 important? How to fix?)

The handle numbers are not important --- that just has to do with
the (not relevant) order of things on the list.  The change from 
e2 to u2 shows that the information that that's an event variable is
getting lost.  I would worry about that.  I think what's happening
is that the question particle is not copying up the verb's INDEX,
though it should be.
