             Summary: stax outTransform may generate duplicate namespace declarations for global attributes
                 Key: CXF-4723
                 URL: https://issues.apache.org/jira/browse/CXF-4723
             Project: CXF
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.7.1
            Reporter: Aki Yoshida
            Assignee: Aki Yoshida


This problem depends on how namespaces are declared for global attributes and when it occurs, the transformed output will contain a duplicate namespace declaration.

Concretely, the outTransform feature transforms the input:
  <soap:Header>
    <Action xmlns="http://www.w3.org/2005/08/addressing">http://apache.org/hello_world_soap_http/Greeter/greetMeRequest</Action>
    <customer:CustomerKey xmlns="http://www.w3.org/2005/08/addressing" xmlns:customer="http://example.org/customer" xmlns:wsa="http://www.w3.org/2005/08/addressing" wsa:IsReferenceParameter="1">Key#123456789</customer:CustomerKey>

into the non-wellformed output containing a duplicate namespace declaration for wsa:
  <soap:Header>
    <Action xmlns="http://www.w3.org/2005/08/addressing">http://apache.org/hello_world_soap_http/Greeter/greetMeRequest</Action>
   <customer:CustomerKey xmlns="http://www.w3.org/2005/08/addressing" xmlns:customer="http://example.org/customer" xmlns:wsa="http://www.w3.org/2005/08/addressing" xmlns:wsa="http://www.w3.org/2005/08/addressing"  wsa:IsReferenceParameter="1">Key#123456789</customer:CustomerKey>
