Places where UD contains information not expressed in CGEL trees

[nschneid]

• xcomp (see Add paths to deep syntactic dependents (control/raising, depictives/resultatives)? #11)
• V: VERB vs. AUX, aux vs. cop (though the latter distinction gets lost with ellipsis if the AUX is promoted)
• proper names (would be better at the level of the whole name than PROPN?)
• minor terminological note: Obj covers obj in a monotransitive clauses as well as prepositional objects, which are heads in UD

[nschneid]

• :tmod (but maybe that's just a semantic distinction we don't need)
• internal structure of certain MWEs? numbers, dates, etc.

[aryamanarora]

For names, I have introduced a Flat structure:

(Nom
    :Head (Flat
        :Flat (N :t "Aryaman")
        :Flat (N :t "Arora")))
