This is an example schema:

         <xs:element name="foo" maxOccurs="unbounded">
           <xs:complexType>
             <xs:sequence minOccurs="0" maxOccurs="unbounded">
               <xs:element name="bar">
                 <xs:complexType>
                   <xs:attribute name="str" type="xs:string"/>
                 </xs:complexType>
               </xs:element>
             </xs:sequence>
             <xs:attribute name="id" type="xs:int"/>
           </xs:complexType>
         </xs:element>
