A mechanism to relate the portType(s) of an event source Web Service to the
abstract description of the events it can produce is needed. 
This mechanism cannot be solely based on WS-MetadataExchange, as this
information may be needed by clients at design time, before any service
endpoints are available. 
The draft replaces the previous mechanism for advertising events produced by a
source, based on a portType extension (using both the wse:EventSource attribute
and notification and solicit/response operations), by two new mechanisms, one
introducing a new language (Event Descriptions), the second one using a WSDL
definition for the sink. 
Both mechanisms provide an abstract description of the events, but no
mechanisms to relate them to the portType of the event source. Rather, it is
suggested to use new WS-Eventing dialects in conjunction with
WS-MetadataExchange to retrieve the descriptions at runtime.
