  50   This module contains the definitions for the objects, inline
  51   elements, and so on that are available to be used as the main
  52   content of DocBook documents.  Some elements are useful for general
  53   publishing, and others are useful specifically for computer
  54   documentation.
  55
  56   This module has the following dependencies on other modules:
  57
  58   o It assumes that a %notation.class; entity is defined by the
  59     driver file or other high-level module.  This entity is
  60     referenced in the NOTATION attributes for the graphic-related and
  61     ModeSpec elements.
  62
  63   o It assumes that an appropriately parameterized table module is
  64     available for use with the table-related elements.
  65
  66   In DTD driver files referring to this module, please use an entity
  67   declaration that uses the public identifier shown below:
  68
  69   <!ENTITY % dbpool PUBLIC
  70   "-//OASIS//ELEMENTS DocBook XML Information Pool V4.5//EN"
  71   "dbpoolx.mod">
  72   %dbpool;
  73
  74   See the documentation for detailed information on the parameter
  75   entity and module scheme used in DocBook, customizing DocBook and
  76   planning for interchange, and changes made since the last release
  77   of DocBook.
