java - Creating a custom JAXB annotation -

People have any recommendations on how to write a custom JXB annotation handling class to support the generation of XS Annotation / Xs: Document element in the xsd schema. I would like to create a new Java annotation "@xll annotation" which will include the "documentation" attribute. Then I made these classes available for JAADAB schema generator through classes. Schema generator will then take this sample Java code

  @XmlRootElement (name = "ClientData") public class ClientData {/ ** * person's first address field * / @Xml Annotation = "Customer's First Address Field") Private String Address1 = Faucet; }  

and make this XSD schema

Will it be easy to extend from existing @ XMLLot Annotation class and just add support for an additional document feature?
