Many of our differences with Carlson and Marcu (2001), who defined EDUs for the RST Discourse Treebank (Carlson et al., 2002), are due to the fact that we adhere closer to the original RST proposals (Mann and Thompson, 1988), which defined as 'spans' adjunct clauses, rather than complement (subject and object) clauses.
we propose that complements of attributive and cognitive verbs (He said (that)..., I think (that)...) are not EDUs.
