[Java SDO] - Is name mangling on generated Java package necessary?

[Fuhwei Lwo]

I ran XSD2JavaGenerator with namespace like 
test.sca.ws.static.import.schema.helloworld and the Java package was generated 
with test.sca.ws.static_.import_.schema.helloworld.  Is this type of name 
mangling necessary?  Thanks.
