+  This module contains the definitions for the overall document

+  
+  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

+  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
