Hi,

I'm in the process of migrating jaxb code to jibx as part of a proof of concept (performance
issues with JAXB).

We use the xsd2jibx tool to generate the Java code and binding xml files.  All schemas are parsed
correctly, but the binding-compiler chokes on one.  I put some work into finding the cause of the
error and trimmed the XSD to the bare minimum, while still getting the error.

Is this a known bug?  Can I get around it without changing the XSD?

XSD:

<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema 
   attributeFormDefault="unqualified"
   elementFormDefault="qualified"
   targetNamespace="https://www.blabla.com/services/entry/1.xsd"
   version="0.9"
   xmlns:xsd="http://www.w3.org/2001/XMLSchema"
   xmlns:cwsce="https://www.blabla.com/services/entry/1.xsd">

   <xsd:complexType name="part"> 
   </xsd:complexType>

   <xsd:complexType name="Parts">
      <xsd:sequence>
         <xsd:choice maxOccurs="1" minOccurs="1">
            <xsd:element maxOccurs="1" minOccurs="1" name="p1Part" type="cwsce:p1Part"/>
            <xsd:element maxOccurs="1" minOccurs="1" name="p2Part" type="cwsce:p2Part"/>
         </xsd:choice>
      </xsd:sequence>   
   </xsd:complexType>

   <xsd:complexType name="p1Part">
      <xsd:sequence>
         <xsd:element maxOccurs="unbounded" minOccurs="0" name="claimPart" type="cwsce:part"/>
      </xsd:sequence>   
   </xsd:complexType>
   <xsd:complexType name="p2Part">
      <xsd:sequence>
         <xsd:element maxOccurs="unbounded" minOccurs="0" name="claimPart" type="cwsce:part"/>
      </xsd:sequence>   
   </xsd:complexType>

</xsd:schema>
