Well, there are a bunch of other options for those as well.  The best place to 
look is actually the **Factory things  (like SOAPTransportFactory, 
SOAPBindingFactory, CORBABindingFactory, etc...)  OR the META-INF/cxf/cxf-
extension-****.xml files.    They have defined namespaces that can be used.  
For example, for (5), the cxf-extension-corba.xml file defines:

				<value>http://cxf.apache.org/bindings/corba</value>
	        	<value>http://schemas.apache.org/yoko/bindings/corba</value>

and either of them can be used.  (the latter is historical as the CORBA 
binding originated from the Yoko project)  Also note: for the CORBA case, the 
binding and transport ID's would be the same as CORBA is both the binding and 
the transport.

Well, #2 is not likely possible.   CXF doesn't support ENCODED at all so we 
PROBABLY have places where LITERAL is just hard coded.

For 1 and 3, you would need to create your own subclass of 
org.apache.cxf.service.factory.AbstractServiceConfiguration
and override whatever methods you want to control.   Then configure that into 
the ServiceFactoryBean in the JaxWsServerFactoryBean at the beginning of the 
ServiceConfiguration list.  Basically, the ReflectionServiceFactoryBean uses 
the list of ServiceConfiguration to retrieve pretty much all the information 
it needs.  JAX-WS has a subclass that gets that information from Annotations, 
but you can easily create your own that gets that information from elsewhere.
