Doug,
 
Mode attribute in WS-E is to specify the additional required event
delivery behavior or required application/business logic extensions that
the event source must understand/support before being allowed to accept
the event subscription.
 
My understanding is: "push_event_thru_proxy" is for all events delivery
from the Subscribe. As such, it covers SubscriptionEnd event. The Mode
attribute also allows to specify fine grained application logic to
control the event delivery.  If you want, more fine grained event
delivery logic/procedure can be easily added to Mode attribute to
control the event delivery, e.g.
"push_thru_proxy_for_subscriptionend_event_only",
"push_thru_proxy_for_non_subscriptionend_event", etc. 
 
Mode attribute in WS-E provides a standard extension point to add
application specific logic and behavior to event delivery, so that it
can enforce the required procedure/logic for business applications when
using WS-Eventing for event delivery.
 
Thanks,
 
- Wu Chou.
