The Meaning of a WSD

Add something like:
This specification defines both the WSDL 2.0 language (i.e., the set of legal sentences in this language and their semantics) and a class of WSDL 2.0 conformant processors.  A Web service description (WSD) is the set or components represented by a legal sentence in the WSDL 2.0 language, as specified in this document.  Endpoints in the WSD describe alternate ways for a provider agent and a hypothetical requester agent to interact.  Each endpoint partially defines the expected interaction between the provider agent and the hypothetical requester agent.  @@ Need to explain why it only "partially defines" the interaction. @@

@@ Need to describe the dependency chain of meaning: The meaning of an endpoint depends on the meaning of the binding and interface, etc. @@

@@ Need to say that a WSD makes a set of assertions about the interaction between the parties in the MEP.  @@
