The W3C made XInclude 1.0 a full recommendation yesterday!
Full details are available at: http://www.w3.org/TR/2004/REC-xinclude-20041220/.
XIncludes will make merging XML documents a reality. Here's a simple syntax example from the W3C site:
<?xml version='1.0'?> <document xmlns:xi="http://www.w3.org/2001/XInclude"> <p>120 Mz is adequate for an average home user.</p> <xi:include href="disclaimer.xml"/> </document>
