/****************************************************************

*  WML Script Proxy Callback implementation. This file implements

*  all the wml script proxy callbacks. Most of the functions are 

*  trivial they just invoke the script interfaces on the WML Script 

*  content handler. The dialog libraries and the error api are not

*  currently under a interface; the content handlers should exhibit

*  the same behaviour for these. TODO : hook up the dialog libraries

*  and the error dialog to the generic dialog api.
