complexType implements or extends other java

[hockeydave007]

I am using jaxb to create my java class and I would like the created class to have additional attributes like:
extends java.io.Seriali zable
implements my.com.Interfac e

<xs:complexTy pe name="class-name">

translated to:
public class ClassName extends java.io.Seriali zable {
}

Is there some way to do this?

Thanks.
