<!--
  This module contains the definitions for the overall document
  hierarchies of DocBook documents.  It covers computer documentation
  manuals and manual fragments, as well as reference entries (such as
  man pages) and technical journals or anthologies containing
  articles.
  
  This module depends on the DocBook information pool module.  All
  elements and entities referenced but not defined here are assumed
  to be defined in the information pool module.
  
  In DTD driver files referring to this module, please use an entity
  declaration that uses the public identifier shown below:
  
  <!ENTITY % dbhier PUBLIC
  "-//OASIS//ELEMENTS DocBook Document Hierarchy V4.2//EN"
  "dbhierx.mod">
  %dbhier;
  
  See the documentation for detailed information on the parameter
  entity and module scheme used in DocBook, customizing DocBook and
  planning for interchange, and changes made since the last release
  of DocBook.
