Peizhao,
We don't need to change the schema, only annotate it.
Or possibly, a single binding in the .xjb file might
do the job.
Probably not, so its only a matter of annotating the
schema at these places with a <jaxb:property name="AbsElementName"/>
for example to direct the parser around the conflict.
