cxf transform feature for Declarative transform in camel route

I have a camel route that starts with a cxfEndpoint1 (consumer) that works as
a CXF server and represents the interface defined in wsdl1. The route is a
pass-through route that sends to a backend web service using CXFEndpoint2
(producer) pointing to wsdl2.

The interface for wsdl1 (incoming) is slightly different (different element
names, and namespace) than the outgoing wsdl2 interface. We need to
introduce transformation in between that transforms message.

I'd like a strategy for introducing transformation that is declarative and
doesn't force me to write java DOM code or XSLT. I found the CXF transform
feature and it looked promising. I'm using it in my route. But i'm having
some issues.

Is it designed for such a use-case? The problem i have is that the
transform seems to occur on entry before the message "hits" CXFEndpoint1. So
if I apply the transform feature to the CXFEndpoint1 (listener), and the
transform defines namespace or element changes (goal is to conform the
message to wsdl2) then I get an exception that the operation name or
namespace is incorrect. I'm guessing its because by transforming the
message at CXFEndpoint1 at an interceptor that occurs before the message is
validated against WSDL1, so it breaks.

So i'm coming to the conclusion that the transform feature is not a good way
to achieve my goal of a generic all-purpose declarative tranfomration
strategy in a camle pass through route from one CXFEndpoint (consumer) to
another CXFEndpoint (producer).

Can someone deny or confrm my thoughts on this, or recommend an approach to
do this type of declarative mapping / tranform simimilar to CXF transform
feature that would allow me to accomplish?
