With regards the definition of operation:
If an operation associates an input message with...
does this imply that we are not supporting the notification operation style
described in WSDL 1.1?

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.

             Keith,

             Here is an initial draft of definitions.  What do you think?

             Non-Normative Definitions
             =========================

             Web Service
             Software that performs a task on behalf of one or more
Clients, typically
             over a network, using protocols defined in this document.
[This definition
             may change, subject to guidance from the Web Services
Architecture Working
             Group.]

             Client
             Software that makes use of a Web Service, acting as its "user"
or "customer".

             Normative Definitions
             =====================

             Message
             Data to be communicated to or from a Web Service as a single
logical
             transmission.

             Operation
             A single logical action supported by the Service. An operation
associates
             an input message with one or more output or error messages.

             OperationSet (a/k/a "Port Type")
             A logical grouping of operations supported by the Service.

             Binding
             An association between an OperationSet, a concrete protocol
and a data
             format that specifies the protocol and data format that may be
used to
             communicate with the Service.

             Port
             An association between a Binding and a network address that
may be used to
             communicate with the Service.

             Service
             A collection of Ports.
