Fields of sub-types should not be added to the current service field list.

If they are added, then the list of fields for the current service will contain phantom-fields (fields which do not exist for the current service).

Nah...

Fields of subtypes are "possible" fields, not phantom fields. It's important to show them for services which return a parent class object. It's actually a core feature of wsdl2html

Are you letting a class extend a concrete class? People may disagree but that's a little anti-pattern. The problem is when you are given an object of concrete class Bean, you don't know if it is a Bean itself, or a SubBean (its child). Robert Martin C. said something about this problem before.

What you can do is to make Bean class abstract and put all the fields and methods there, and let there be a DefaultBean as it's sunclass without extra implementation, then let your current SubBean to extend the abstract Bean. For a service which only returns the default fields, using DefaultBean. For services that may or may not extra fields, return Bean.
