WS-Eventing

• WSDL 1.1 Message Exchange Patterns (MEPs) include
  one-way, request/response, notification and
  solicit.
• WSDL 2.0 MEPs include Robust In-Only,
  In-Optional-Out, Robust Out-Only and
  Out-Optional-In which are extensions to the four
  MEPs that were defined in WSDL 1.1.

Both specs leverage WS-Addressing and are based
on the pub/sub paradigm.
