Description

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>
