[xsd-users] bug (?) with choice of two sequences with same element

[Eelko de Groot]

When a schema contains a choice of two sequences of elements and both 
sequences contain the same element, the xsd tool produces two 
classes/structs with the same name.
The following example illustrates this problem.
Is there a solution for this?

$ cat test.xsd
<?xml version="1.0" encoding="utf-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
         xmlns:t="test"
         targetNamespace="test"
         version="0.1" elementFormDefault="qualified">

<element name="Test" type="t:TestChoiceType"/>
<complexType name="TestChoiceType">
   <choice>
     <sequence>
       <element name="ElementA" type="string"/>
       <element name="ElementB" type="string" minOccurs="0"/>
     </sequence>
     <sequence>
       <element name="ElementB" type="string"/>
     </sequence>
   </choice>
</complexType>

</schema>

$ xsd cxx-tree --generate-inline test.xsd
$ cat test.hxx

   class TestChoiceType : public ::xsd::cxx::tree::type

     // ElementB1

     {

       typedef ::xsd::cxx::tree::traits< type_ > traits_;
       typedef ::xsd::cxx::tree::optional< type_ > container_;
     };

     public:
     struct ElementB1
     {
       typedef _xsd_ElementB1::type_ type;
       typedef _xsd_ElementB1::container_ container;
     };

     _xsd_ElementB1::container_ const&
     ElementB1 () const;

     _xsd_ElementB1::container_&
     ElementB1 ();

     void

     void
