Non-nillable elements of a group are required even if the group itself is not.
------------------------------------------------------------------------------

         Key: AXIS-2406
         URL: http://issues.apache.org/jira/browse/AXIS-2406
     Project: Apache Axis
        Type: Bug
  Components: WSDL processing  
    Versions: 1.3    
 Environment: Windows 2000, Java 1.4.2_05
    Reporter: Mark Rave


Issue stems from the use of the <xsd:group ref=""> inside of complex type.  What seems to be happening is that even though the group as a whole is nillable the elements of the group are not.  Instead of creating a subtype WSDL2Java places the group elements along with other elements in the type at the same level which means that both elements of the group are required which is not what I want.  I understand that WSDL2Java can't simply create a subtype of its own since that would generate incorrect XML.   I have attached a sample wsdl and code that shows the problem.  I am using the -W option with WSDL2Java.
