Clarify notification channel behavior

 bother notification aware controls that are uninterested in unrelated
 notifications, a notification object is created for each notification.
 
+Note that the notification channel is an identifier and unquoted identifiers
+will be converted to lowercase while \pn{} will attempt to match subscribed to
+notifications exactly. This means that it is generally a good idea to subscribe
+with the channel specified in lowercase.
