Description

If a request message is send to a CXF consumer or a response is returned to the CXF provider that contains namespace definions at the SOAP envelope and the Camel-CXF endpoint is configured in PAYLOAD mode the namespace definition gets lost unless streaming is disabled.

If the resulting CxfPayload is then converted e.g. to String that String will contain invalid XML (because some namespace definition is missing).

For non-streaming mode (system property org.apache.camel.component.cxf.streaming is set to false) there are special precautions met to set these envelope namespaces on the first DOM element of the payload but this coding is missing for StAX.

The messages in question look like that:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<ns2:getTokenResponse xmlns:ns2="http://camel.apache.org/cxf/namespace">
<return xsi:type="xs:string">Return Value</return>
</ns2:getTokenResponse>
</soap:Body>
</soap:Envelope>

If the CxfPayload is converted to String it will lack the definition for the xsi namespace prefix (and further XML parsing will fail).
