Hi all,

below I suggest replacement text for the first paragraph in section 2.2,
schema mappings. The reason for this suggestion is that the current text
is still biased on a scenario of mediation between two different XML
structures, where a simpler scenario is plausible with the client
operating on the semantic level. SAWSDL section 2.2 really only needs to
provide the building blocks, lifing and lowering schema mappings, and
the more complex scenario will be possible.

Suggested rewrite:

        SAWSDL introduces schema mapping annotations to address
        post-discovery issues in using a Web service. Model references
        can be used to help determine if a service meets the
        requirements of a client, but there may still be mismatches in
        the structure of the inputs and outputs. For example, a client
        may have a given name and last name among its data, and these
        values need to be concatenated in the message to the Web
        service. The schema mapping would take the client's semantic
        data and turn it into XML, and in the process it would perform
        the necessary concatenation to produce the full name.
        
        In a more complex scenario, a client may use WSDL with semantic
        annotations to describe the service it expects. Again, if the
        XML structures expected by the client and by the service differ,
        schema mappings can translate the XML structures into the
        semantic model where any mismatches can be understood and
        resolved.

Discussion will be welcome,

Jacek
