The XSD file path is relative to the plugin&apos;s root directory. Here is an example where a plugin adds an XSD file named &apos;extension.xsd&apos; located in the &apos;test_xml_files&apos; directory.
&lt;/p&gt;

&lt;extension
      point=&quot;org.eclipse.tracecompass.tmf.analysis.xml.core.xsd&quot;&gt;
    &lt;xsdfile
         file=&quot;test_xml_files/extension.xsd&quot;&gt;
    &lt;/xmlfile&gt;
&lt;/extension&gt;

&lt;p&gt;
The base XSD file has some extension possibilities. There is an &quot;extra&quot; element that can be used as a base to add a new one. The following XSD file adds a new element type to the schema
&lt;/p&gt;

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; standalone=&quot;no&quot;?&gt;
&lt;xs:schema xmlns:xs=&quot;http://www.w3.org/2001/XMLSchema&quot;
 attributeFormDefault=&quot;unqualified&quot; elementFormDefault=&quot;qualified&quot;&gt;

 &lt;xs:element name=&quot;my&quot; substitutionGroup=&quot;extra&quot; type=&quot;myType&quot;/&gt;
 &lt;xs:element name=&quot;abc&quot; substitutionGroup=&quot;extra&quot; type=&quot;myType&quot;/&gt;

 &lt;xs:complexType name=&quot;myType&quot;&gt;
  &lt;xs:complexContent&gt;
   &lt;xs:extension base=&quot;extraType&quot;&gt;
    &lt;xs:sequence&gt;
     &lt;xs:element maxOccurs=&quot;unbounded&quot; minOccurs=&quot;0&quot; name=&quot;mySubElement&quot; type=&quot;xs:string&quot; /&gt;
    &lt;/xs:sequence&gt;
    &lt;xs:attribute name=&quot;name&quot; type=&quot;xs:string&quot; use=&quot;optional&quot; /&gt;
   &lt;/xs:extension&gt;
  &lt;/xs:complexContent&gt;
 &lt;/xs:complexType&gt;

&lt;/xs:schema&gt;
