A Workflow Definition Service is seen as a low priority. It is
unlikely that it will be specified before 2005.
This service may not be needed, particularly for the vast
majority of service chains that are enacted. Domain-specific
applications could contain definitions of standard sequences of
operations, and to facilitate the calling of these services.
Service chaining may not become a service per se but a set of
operations embedded inside a large number of domain related
application services that will allow those applications to
dynamically chain to other services based on service discovery
operations.
It may be possible to choose a generic web technology solution
for this service.
