Description

I want to use XML XInclude mechanism (http://en.wikipedia.org/wiki/XInclude) to include parts of schema.xml.
When I try to include a fieldType, I get this exception :

java.lang.RuntimeException: schema fieldtype string2(org.apache.solr.schema.StrField) invalid arguments:

{xml:base=solrres:/schema_integration.xml}

I include 'schema_integration.xml' like this :

schema.xml ->
<?xml version="1.0" encoding="UTF-8" ?>
<schema name="default" version="1.1">
<types>
<!-- Stuff -->
<xi:include href="schema_integration.xml" xmlns:xi="http://www.w3.org/2001/XInclude"/>
</types>

<!-- Stuff -->
</schema>

schema_integration.xml ->
<?xml version="1.0" encoding="UTF-8" ?>
<fieldType name="string2" class="solr.StrField" sortMissingLast="true" omitNorms="true"/>
