* Contains a localized message key, it's arguments and a {@link I_CmsMessageBundle}.
*
* Used for delaying the actual message lookup from the bundle to the time the message is displayed,
* not generated. This is used for localizing internal OpenCms messages. If a message is generated internally by OpenCms,
* at the time no information about the context of the current user may be available. The message is therefore
* passed to the class generating the output, where a user context usually exists. Finally, the message is rendered
* with the locale of the available user, or the OpenCms default locale if no user is available.
