This is running on java 1.6.0_26, and jetty 7.4.4.v20110707.
The stack trace in the case of the use of the fragment is:
2011-07-13 18:52:42,953 [main] ERROR org.apache.solr.core.Config -
Exception during parsing file:
solrconfig.xml:org.xml.sax.SAXParseException: Fragment identifiers
must not be used. The 'href' attribute value
'../../conf/solrconfigIncludes.xml#xpointer(root/node())' is not
permitted.

I did attempt the xpointer="xpointer(//requestHandler)" syntax, and
received this error: 2011-07-13 18:49:06,640 [main] WARN
org.apache.solr.core.Config - XML parse warning in
"solrres:/solrconfig.xml", line 3, column 133: SchemeUnsupported: The
XPointer scheme 'xpointer' is not supported. This matches what the
wiki page indicates, and the Xerces FAQ confirms, which is that Xerces
does not support the xpointer() scheme. I was not able to find any
indication that there was any Java libraries available that do support
the xpointer scheme. If anyone knows of one, and how to configure
Solr to use it, that would almost certainly fix my problem.
I do understand that Solr isn't doing anything special with XInclude.
But from my attempts to understand the state of XInclude on the JVM, I
am unable to identify a useful technique for taking advantage of it to
share configuration in Solr. My hope was that someone who had used it
successfully could indicate either something I missed about how to
make it work, or a useful pattern for working within the limitations
of the available functionality.
