         There are several sections below:

             Basic Types. General-purpose elements used everywhere.

             Abstract Classes. Unions of concrete types.

             List Types. Lists of abstract class types.

             Boolean Elements. These indicate that the corresponding
             query is True; False is indicated by Nil.

             Defining Occurrences. Elements for defining occurrences,
             such as Defining_Identifier.

             Usage Occurrences. Elements for usage occurrences
             (references to defining occurrences), such as Identifier.

             Other Elements. All syntactic structures that don't fall
             under defining or usage occurrences.
