ExtensionsData in Browser Binding

[Marie-Luise Kuhlmann]

Hello
 
I want to use ExtensionsData parameter in the server API in some functions 
(updateProperties), but I find some differences in the bindings. With web 
services I can use the ExtensionsData parameter, with ATOMPUB I add 
ExtensionsData to the properties parameter but how can I manage that with 
browser binding?
 
 
Regards
