How to have CXF work with external JAXB bindings file?

[KARR, DAVID (ATTCINW)]

I'm trying to experiment with an external JAXB bindings file with CXF.
Will the specs in this be used at marshalling time to allow for
massaging of the output, or is this only intended to be used for code
generation?  If it can be used at marshalling time, where exactly do I
put it?  Do I have to indicate its presence in the CXF configuration
somehow?
