XML itself may not have a notion of inclusions, but you could still 
emulate them. To use the five minute tutorial's example:

     <debug>
         <filename>debug.log</filename>
         <pt:include src="debug-modules.conf" />
         <level>2</level>
     </debug>

and in debug-modules.conf, you'd have:

     <modules>
         <module>Finance</module>
         <module>Admin</module>
         <module>HR</module>
     </modules>

This could pose problems with interoperability, depending what other 
programs and libraries you include to use the XML file with. Another 
problem is that while this could be done in the parser, it may be more 
suited elsewhere.
