    Hi,

    To clarify a little...

    PSI conformance print services and target devices MUST publish
    URLs for the WSDL for each of their supported interfaces (see
    my revised conformance requirements message earlier today).

    Tools exist that convert WSDL to appropriate SOAP messages.

    A "SOAP binding" is a definition of SOAP message _transport_
    over HTTP, SMTP, BEEP, or whatever (those three are currently
    standardized).

    For interoperability, clients and servers need to be able to
    consume and validate published WSDL definitions of other PSI
    servers.

    For interoperability, all PSI/1.0 clients and servers MUST
    support the HTTP/1.1 transport binding of SOAP/1.1.

    Separately, PSI/1.0 doesn't (yet) require support for UDDI
    based discovery. I question the desirability of adding a
    UDDI infrastructure dependence to all PSI/1.0 implementations.

    Cheers,

    Subject: PS> Mandatory binding

    During today's conference call the topic of a mandatory binding came up.

    We would prefer to publish the interface and binding WSDL separately and
    define a discovery method. We're not sure if UDDI is too coarse a discovery
    method for this purpose.
