Also: 1-4 and 1-5?

How can you tell for example that (1 (3 )3 (5 )5 (3 )3 )1 is valid but
(1 (3 )3 (3 )3 )1 is not valid for this grammar? Is the set of valid
phrases just given, in addition to the allowable nestings, at this
point?

How is the role of CU taken into account? It's presence/absence will
play a role in whether a preceding )2 can be elided or not.
