If the parameters can refer to the complex types (as opposed to simple 
types) then, with a BeanValidation aware JAXB plugin (the one linked to 
before), then a Java class with BeanVal annotations can be produced, 
this is what led to updating wadl-to-java adding @Valid annotations if 
"-beanValidation" option is set.
Am I missing something ?
