Castor generate classes for complextype not working

Hi I have following which is not generating class file for complextypes using bindigs.xml file.

Sample.xsd file

<?xml version="1.0" encoding="UTF-8"?>

bindings.xml

<binding xmlns="http://www.castor.org/SourceGenerator/Binding"

            xsi:schemaLocation="http://www.castor.org/SourceGenerator/Binding
                C:\\Castor\\xsd\\binding.xsd" 
            defaultBinding="element">

   <elementBinding name="/Data/PurchaseOrder/LineItem">
      <java-class name="PurchaseOrderLineItem"/>
   </elementBinding>

   <elementBinding name="/Data/OrderReceipt/LineItem">
      <java-class name="OrderReceiptLineItem1"/>
   </elementBinding>

   <elementBinding name="/complexType:ReceiptLineItemType/Sku">
      <java-class name="Xxxxxx"/>
   </elementBinding>

   <elementBinding name="/complexType:LineItemType/Sku">
      <java-class name="Yyyyyy"/>
   </elementBinding>    

</binding>

pom.xml plugin configuration :

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>castor-maven-plugin</artifactId>
    <version>1.0</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <bindingfile>src/main/castor/binding.xml</bindingfile>
        <schema>src/main/castor/sample.xsd</schema>
        <packaging>com.sg.defi.castor.correspondence</packaging>
        <properties>src/main/castor/castorbuilder.properties</properties>
    </configuration> 
</plugin>

Is there anything to be changed in any .properties file , inorder to get class files generated with the name given bindings.xml file for complextypes.

Figured it out ! ,

Modify the binding.xml for complextypes to

<elementBinding name="/complexType:ReceiptLineItemType/Sku">    
   <java-class name="Xxxxxx"/>  
  </elementBinding> 

Change the above code to 

<complexTypeBinding name="complexType:ReceiptLineItemType/Sku">    
   <java-class name="Xxxxxx"/>  
</complexTypeBinding> 

Very sadly the castor website itself posted the example in a wrong way
