Description

With a doc/literal endpoint using PAYLOAD mode, if a client sends a request where the child element of the Body uses a default namespace and that namespace is defined on the soap envelope or soap body (and not the element itself), you either get an exception of:

1) (insecure message, no WSS4J processing)

org.xml.sax.SAXParseException: Element or attribute do not match QName production: QName::=(NCName':')?NCName. 
    at org.apache.camel.impl.converter.BaseTypeConverterRegistry.createTypeConversionException(BaseTypeConverterRegistry.java:610)[75:org.apache.camel.camel-core:2.16.3]
    at org.apache.camel.impl.converter.BaseTypeConverterRegistry.convertTo(BaseTypeConverterRegistry.java:137)[75:org.apache.camel.camel-core:2.16.3]

2) Secure message:

org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.

    at org.apache.camel.component.cxf.DefaultCxfBinding.addNamespace(DefaultCxfBinding.java:764)[76:org.apache.camel.camel-cxf:2.16.3]

both are due to camel-cxf/DefaultCxfBinding.addNamespaces not properly adding default namespace attributes to the DOM.
