The ultimate thing would be to use JAXB Models, namely
com.sun.xml.bind.v2.model.runtime.RuntimeTypeInfoSet. It has the
complete information of the JAXB model used for marshalling and
unmarshalling.
Brief outline:
* Create com.sun.xml.bind.v2.runtime.JAXBContextImpl or cast to it
from JAXBContext (JAXB RI only)
* context.getTypeInfoSet()
* typeInfoSet.getType(Bar.class)
* classInfo.getProperty("test")
* attributePropertyInfo.getXmlName() is what you need
Very adult usage of JAXB.
