Description

The xinclude tag does have xpointer support as per http://www.w3.org/2001/XInclude which helps include specific tags from external xml's. Please support xpointer in solr as well. This will help in modularization and reusability.

Eg:
child.xml =
<root>
<field>1</field>
<field>2</field>
</root>

schema.xml =
<fields>
<xi:include href="child.xml" xpointer=(//root) xmlns:xi="http://www.w3.org/2001/XInclude">
</fields>
