Anne, Hao,

I agree with Anne's reply indicating that the choice between RPC or 
document-style does not mandate a particular client programming style. The 
WSDL spec e.g. specifically says that "This information _may_ be used to 
select an appropriate programming model".

However, while I understand that you can do document-style messaging using 
normal stubs, I'm also interested in scenarios where the messages have 
more variable format (an unknown number of documents, each with optional 
attachment, say) than is typical for RPC (three integer parameters, say). 
For handling sg. like this an approach with callback handlers (like Hao 
seems to indicate as well) seems like an attractive option to me. I'd be 
curious to learn more about existing approaches esp. of this kind.

Regards,
Christian
