Schema Help

Title: Message

One of the complexTypes in my schema as below:

 

 <xsd:complexType name="ExtendedDataElementType">
  <xsd:sequence>
   <xsd:choice>
    <xsd:element maxOccurs="unbounded" minOccurs="0" name="values">
     <xsd:simpleType>
      <xsd:restriction base="xsd:string">
       <xsd:maxLength value="1024"/>
      </xsd:restriction>
     </xsd:simpleType>
    </xsd:element>
    <xsd:element maxOccurs="1" minOccurs="0" name="hexValue" type="xsd:hexBinary"/>
    <xsd:any namespace="##any" minOccurs="0" maxOccurs="unbounded"/>
   </xsd:choice>
   <xsd:element maxOccurs="unbounded" minOccurs="0" name="children" type="cbe:ExtendedDataElementType"/>
  </xsd:sequence>
 </xsd:complexType>

 

When I use Xerces (2.4.0) to validate a xml against the schema with the "schema full checking" on, and getting the following error:

 

[Error] test.xsd:522:50: cos-nonambig: "http://someNameSpace":values and WC[##any] (or elements from their substitution group) violate "Unique Particle Attribution".

I think the complex type is not valid, but I don't know what's wrong, can someone help me how this complex type should be?

 

Thanks,

Benson.
