title: tell jaxb to not remove underscores
body: <p><br/>Is there a way to tell JAXB to not remove underscores when creating getter/setter names from XML Schema?<br/>
  Reason: this causes loss of information and it is harder to trip between XML and Java; e.g. in written communications where one participant might be confused about "different names".
  <br/></p>
  
  <p>Example: NR_ROR should not become getNRROR but getNR_ROR.
  <br/>
  Note: I believe that the less-mangled names are worth the "violation" of Java naming convention.<br/>
  TIA<br/>
