!!! Overview
[{$pagename}] is applied to any event that comes from [EDirectory] and is used to filter out any events from [EDirectory] that are of interest to the implementation of the driver.

Only events that are __NOT__ filtered out of the [{$pagename}] are allowed to reach the [Event Cache] and therefore any part of the [Subscriber Channel]
