use-case is:

• if a user does not want to expose directly its entities, he needs to provide some DTOs with @javax.xml.bind.annotation.XmlRootElement annotation (so that the JAX-RS runtime can unmarshall/marshall the request and response bodies).

These DTOs coding could be automated by a wizard which would let the user select the POJO fields and choose his prefered annotation style (field vs method) and output package
