How to hardwire XML namespace prefixes when generating from schema?

[KARR, DAVID]

I have one CXF project using version 2.3.2 (and others using newer versions).  
This project generates the JAXB classes from schema.  I'd like to hardwire the 
namespace prefix we use.  I can see how to do that with hand-coded JAXB classes 
in the package-info class, but I'm not sure how to make that happen from 
schema.  Is there a way to do this?
