failing namespace resolution after CXF-5891 after updating from JBoss EAP 6.2 to JBoss EAP 6.3 CP3

Issue

• Failing namespace resolution for SOAP request. After updating from EAP 6.2.3 to 6.3.3, one of our clients reported a problem with a web service that previously worked fine, but in 6.3.3, the response is a SOAP fault with the message "prefix xs is not bound to a namespace". Any namespace defined in the Body element is not considered any more. The problem only occurs when defining one or more SOAP handlers.
