!!! Overview
[{$pagename}] is the [entity] that causes the [XDAS Event] to occur by taking action against the [XDAS Target].

The [{$pagename}] of an event is the [authenticated] entity that initially provoked creation of the [XDAS Event]. 

!! Special Cases
The [{$pagename}] need not be identified. 

If the entity can't be identified - perhaps an [entity] is attempting to login, thus provoking the generation of a login event by an [XDAS Observer] - then as much information about the origin of the event as possible should be specified. 

! Login Event
In the special case of a login event, the authenticated identity of the [{$pagename}] is not yet known until after the login attempt has succeeded. Therefore a failed login event should not give the identity of the [XDAS Target] account as the identity of the [{$pagename}].
