Bug description:  disappearing xi:include tags?

Description:
------------
I'm trying to include all the xi:include tags in a file but PHP seems 
to just ignore some of them. 

I'm using XML's that are known to work 100%. You can see the XML 
files here:
http://postbooks.svn.sourceforge.net/viewvc/postbooks/xtupledocs/trun
k/referenceguide.tar.gz?view=tar

Basically the problematic file is products.xml which is included from 
referenceguide.xml and contains more includes. They all get ignored.

Reproduce code:
---------------
...
echo "Importing XML document...\n";
        $document = new DOMDocument();
        $document->load( DOCBOOK_PATH );
        
        echo "Parsing <xi:include> tags...\n";
        xinclude_all( $document );
...

        function xinclude_all( &$document ){
                $counter = 0;

                $xpath = new DOMXPath($document);
                $xpath->registerNamespace('xi', $ns =
'http://www.w3.org/2001/XInclude');
                $includes = $xpath->query( "//xi:include" );
                
                while($includes->length){                       
                        $counter++;
                        echo "Parsing <xi:include> layer number $counter. 
{$includes->length}
<xi:include> tags on this layer. ";
                        $document->xinclude();
                        $includes = $xpath->query( "//xi:include" );
                        echo "{$includes->length} includes to process on next 
layer\n";
                }
                
                echo "$counter <xi:include> tag levels parsed.\n";
        }


Expected result:
----------------
I expect all the includes to be parsed and included.

Actual result:
--------------
Only the 12 includes in the main referenceguide.xml file get 
included, then it just says that there is no need to further include 
as if there were 0 more includes in the DOM tree.
But the included data isn't there.
