This tree, which can be anchored by a comma, dash or colon, handles
asymmetric (peripheral) NP appositives and NP colon expansions of
NPs. Figure 24.3 shows this tree anchored by a dash and a
colon. Like the symmetric appositive tree, nxPUnxpu, the
asymmetric appositive cannot be a pronoun, while the colon expansion
can. Thus, this constraint comes from the syntactic entry in both
cases rather than being built into the tree.

The colon expansion cannot itself contain a colon, so the foot S has the
feature NP.t:
