[castor-user] XSD Mapping Question

[Ronald R. DiFrango]

All,

I have the following XSD fragment:

<xs:element name = "detailLine">
       <xs:complexType>
           <xs:sequence>
               <xs:choice>
                   <xs:element ref = "rtvNumber"/>
                   <xs:element ref = "cmNumber"/>
                   <xs:element ref = "keyRecNo"/>
               </xs:choice>
               <xs:element ref = "lineNumber"/>
               <xs:element ref = "brand"/>
               <xs:element ref = "class"/>
               <xs:element ref = "model"/>
               <xs:element ref = "originalQuantity"/>
               <xs:element ref = "availableQuantity"/>
               <xs:element ref = "itemCost"/>
               <xs:element ref = "extendedCost"/>
               <xs:element ref = "cmRtvNumber" minOccurs = "0"/>
               <xs:element ref = "effectivePrice" minOccurs = "0"/>
               <xs:element ref = "adjustment" minOccurs = "0" maxOccurs =
"unbounded"/>
               <xs:element ref = "status"/>
           </xs:sequence>
       </xs:complexType>
   </xs:element>

By default, Castor is generating another class to handle the choice
element.  is there a way to create a binding such that it creates these as
"optional" elements at the top level of the DetailLine class?

Thanks in advance,

Ron
