What does streaming=on do for server message processing?

[Charles Roy]

Hi,
I was wondering what the "streaming=on" attribute in the WSDD for a RPC 
service does for Axis 1.1 as compared to 1.2?

Does it setting streaming=on prevent the creation of the serialized 
return message being stored in a string and/or buffer by Axis on the 
server before it is output to the client?

Thanks,
Charles
