> It seems like there are a few related problems when a Java method has multiple outputs, as my test will show. 
> I think the history here is:
> - We first added support for using a single Holder parm (with INOUT or OUT) but only in the case in which there was only one output altogether, (i.e. the return type was void).
> - Brent recently added some support for truly using multiple outputs.
> I'm not sure what if any tests we have though using multiple outputs.  For example, the test in 
> samples/learning-more/binding-ws/holder-ws-service only has a single output.
> However, I do have a guess at how this might have worked at some point (maybe for Brent).    
> I think if we have a binding/wire configuration which uses MediatorImpl.copyInput, etc, it might work with the existing code.   However, I think when we use the DataTransformationInterceptor which in a typical Java<->XML transform uses the Input2InputTransformer, etc., it exposes holes in the wrapping that need to be more fully implemented.
> I'll attach a test.    
> In the meantime I've assigned to myself as I have started working on a few areas including the Input2Input, Output2Output transformers, the JAXWS interface processor.  Also the wsdlgen will need some tweaking I think.
