I * was interested in only going from java -> XML representation. * * Why is there a xml: prefix ? * * c. A few seconds later I realized that this was because I was * was attempting to marshal a type. Although the use of xml:prefix * Since I am closely involved with JAXB 2.0, I was able to figure * this out.
