The chapter on nouns, for example, identifies five species (common, proper, collective, concrete, abstract) and five applications (subject, complement of verb, object of preposition, appositive, direct address).

However, they did not take into account appositive adnoun clauses but only considered relative adnoun clauses.
The category 'appositive' is not taken into account for fair comparison.
The key task is to determine the relation between the two constituents in terms of such functional categories as subject, object, adverbial and appositive.
Appositive structures, conjunctions, disjunctions and the like are all handled by minor blocks.
