<br><font size=2><tt>Hi,<br>
<br>
To clarify a little...<br>
<br>
PSI conformance print services and target devices MUST publish<br>
URLs for the WSDL for each of their supported interfaces (see<br>
my revised conformance requirements message earlier today).<br>
<br>
Tools exist that convert WSDL to appropriate SOAP messages.<br>
<br>
A "SOAP binding" is a definition of SOAP message _transport_<br>
over HTTP, SMTP, BEEP, or whatever (those three are currently<br>
standardized).<br>
<br>
For interoperability, clients and servers need to be able to<br>
consume and validate published WSDL definitions of other PSI<br>
servers.<br>
<br>
For interoperability, all PSI/1.0 clients and servers MUST<br>
support the HTTP/1.1 transport binding of SOAP/1.1.<br>
<br>
Separately, PSI/1.0 doesn't (yet) require support for UDDI<br>
based discovery. I question the desirability of adding a<br>
UDDI infrastructure dependence to all PSI/1.0 implementations.<br>
<br>

Subject: PS> Mandatory binding<br>
<br>
<br>
<br>
During today's conference call the topic of a mandatory binding came up.
<br>
<br>
We would prefer to publish the interface and binding WSDL separately and<br>
define a discovery method. We're not sure if UDDI is too coarse a discovery<br>
method for this purpose. <br>
