    40 Abstract base class for WAP Push Application plugins.
    41 
    42 A WAP Push Application plugin is implemented as an ECom plug-in object that 
    43 derives from this interface. Each plugin specifies in its ECom IMPLEMENTATION_INFO 
    44 default_data field the Push Application IDs that it should handle. When the 
    45 WAP Push Framework receives a push message, it examines the message's Application 
    46 ID, and loads the appropriate plug-in to handle the message with HandleMessageL().
    47 
    48 A plug-in can handle multiple Application IDs. Application IDs can be specified 
    49 as URNs or WINA (http://www.wapforum.org/wina/push-app-id.htm) values. For 
    50 example, a plug-in to handle MMS would set its default_data to "x-wap-application:mms.ua||0x00000004".
    51 
    52 A plug-in must destroy itself when it is has finished handling the message. 
    53 The framework supplies a CPluginKiller object that the plug-in calls to do 
    54 this.
