> For some sequences containing structs and/or structs containing sequences 
> there is a wrong WSDL generated (at least the generated Axis2 Java Stubs 
> produce an XML that results in a wrong Corba call). At runtime this results 
> in the Orb complaining about NULL elements being marshalled.
> To reproduce: Take the sample from http://wso2.org/library/2807 and include 
> these IDL definitions:
>    struct B {
>            string s;
>      };
>      
>      struct A {
>            sequence<B> Bseq;
>            string x;
>      };
>      
>      typedef sequence<A>  Aseq; 
>      
>     interface MyCorbaService 
>     { 
>           
>        void testSeq(in Aseq pAs);
> this results in the WSDL snipped below. The representation for string x 
> should be outside of the xs:sequence.
