The internal subset augments the document DTD.

If the following, the document DTD is document referenced by
"-//OASIS//DTD DocBook XML V4.1.2//EN" while the internal subset contains
the extra <!ENTITY> aspects.  


<?xml version="1.0"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN"

        <!ENTITY gentle-intro   SYSTEM "gentle-intro.xml">
        <!ENTITY overview       SYSTEM "overview.xml">
        <!ENTITY productions    SYSTEM "productions.xml">
        <!ENTITY handler        SYSTEM "handler.xml">
        <!ENTITY event-source   SYSTEM "event-source.xml">
        <!ENTITY reader         SYSTEM "reader.xml">
        <!ENTITY readerfactory  SYSTEM "readerfactory.xml">
