RE: Draft of Definitions

Some minor edits:
 
Message
Application specific data to be communicated as a single logical transmission.

Operation
A set of messages that correlate to a single action. An operation associates an input message with zero or more output and error messages.

OperationSet (a/k/a "Port Type")
A logical grouping of operations.

Binding
An association between an OperationSet and the specific wire format, application protocol, and transport protocol to be used to transmit the messages. <Keith>I don't like this wording much. This is a difficult concept, and seems to be really about three separate but related ideas. </Keith>  

Port
An association between a binding and a network address that may be used to
communicate with the Service. <Keith>This feels uneeded as a normative definition. </Keith>

Service
A logical grouping of bindings.

 OperationSet (a/k/a "Port Type")

 Binding
 An association between an OperationSet, a concrete protocol and a data
