Hi Clemens,
I forgot that XInclude requires well-formed XML, so schema-common.xml without
<schema></schema> tags won’t work, since it will have multiple root elements.
But instead of XInclude, you can define external entities for files you want to
include, and then include a reference to them where you want the contents to be
included.
This worked for me:
——
schema.xml
——
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE schema [ <!ENTITY schema_common SYSTEM "schema-common.incl"> ]>
<schema name="locale_de" version="1.5">
&schema_common;
</schema>
——
——
schema-common.incl
——
<uniqueKey>_my_id</uniqueKey>
<field indexed="true" name="_version_" stored="true" type="long"/>
<copyField dest="_my_suggest" source="_my_title"/>
<fields>
<field indexed="true" multiValued="false" name="_my_id" required="true"
stored="true" type="string"/>
<field indexed="true" multiValued="false" name="_my_title" required="true"
stored="true" type="string"/>
<field indexed="true" multiValued="true" name="_my_suggest" stored="false"
type="string"/>
</fields>
<types>
<fieldType class="solr.StrField" name="string" sortMissingLast="true"/>
<fieldType class="solr.TrieLongField" name="long" positionIncrementGap="0"
precisionStep="0"/>
</types>

Here’s what I get back from curl
"http://localhost:8983/solr/mycore/schema?wt=schema.xml&indent=on”:
——
<?xml version="1.0" encoding="UTF-8"?>
<schema name="locale_de" version="1.5">
<uniqueKey>_my_id</uniqueKey>
<fieldType name="long" class="solr.TrieLongField" precisionStep="0"
positionIncrementGap="0"/>
<fieldType name="string" class="solr.StrField" sortMissingLast="true"/>
<field name="_my_id" type="string" multiValued="false" indexed="true"
required="true" stored="true"/>
<field name="_my_suggest" type="string" multiValued="true" indexed="true"
stored="false"/>
<field name="_my_title" type="string" multiValued="false" indexed="true"
required="true" stored="true"/>
<field name="_version_" type="long" indexed="true" stored="true"/>
<copyField source="_my_title" dest="_my_suggest"/>
</schema>
