+<!--
+  This module contains the definitions for the objects, inline
+  elements, and so on that are available to be used as the main
+  content of DocBook documents.  Some elements are useful for general
+  publishing, and others are useful specifically for computer
+  documentation.
+  
+  This module has the following dependencies on other modules:
+  
+  o It assumes that a %notation.class; entity is defined by the
+    driver file or other high-level module.  This entity is
+    referenced in the NOTATION attributes for the graphic-related and
+    ModeSpec elements.
+  
+  o It assumes that an appropriately parameterized table module is
+    available for use with the table-related elements.
+  
+  In DTD driver files referring to this module, please use an entity
+  declaration that uses the public identifier shown below:
+  
+  <!ENTITY % dbpool PUBLIC
+  "-//OASIS//ELEMENTS DocBook XML Information Pool V4.5//EN"
+  "dbpoolx.mod">
+  %dbpool;
+  
+  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.
