Documentation — Numérotation des divisions et subdivisions dans les documents écrits

Applies to all kinds of written documents, for example manuscripts, printed works, books, journal articles, directions for use and standards. Numbering of divisions and subdivisions is advocated if this - clarifies the sequence, importance and interrelation of individual divisions and subdivisions; - simplifies search and retrieval of certain passages in the text; - makes possible the citation of single parts of the text; - facilitates references within a written work.
