20 /* SPSS Viewer (SPV) file reader.
22 An SPV file, represented as struct spv_reader, contains a number of
23 top-level headings, each of which recursively contains other headings and
24 tables. Here, we model a heading, text, table, or other element as an
25 "item", and a an SPV file as a single root item that contains each of the
26 top-level headings as a child item.

62 returned by spv_get_root(), is always a heading. */
