/** ECom interface UID for WAP Push Content Handler plug-ins. */

/** 

Abstract base class for WAP Push Content Handler plug-ins.

A WAP Push Content Handler plug-in processes a WAP Push message that contains 

data of a specific media type. A Content Handler plug-in is loaded by a WAP Push Application

Handler plug-in (CPushHandlerBase-derived object), and the message is passed to handle 

through HandleMessageL().

A WAP Push Content Handling plugin is implemented as an ECom plug-in object derived from 

the CContentHandlerBase interface.

Each Content Handler plug-in should specify the media type that it handles. Content Handler 

plug-ins can handle multiple media types: for example, a plug-in to handle SI messages can

specify it's media type as "text/vnd.wap.si||application/vnd.wap.sic".
