In general our document are split into some smaller files. We have a master document file and some chapter or section files which will be included by the master document file^[2]. This include files are located within a subdirectory. The complete document will be merged temporary only at conversion time (when the different output formats are generated).

This document for example consists of the following files:

 docroot/src/en/XD-999.xml
 docroot/src/en/docbook/mg_intro.xml
 docroot/src/en/docbook/mg_sample_chapter.xml
 docroot/src/en/docbook/mg_sample_section.xml
