<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal><span style='font-size:14.0pt;color:#1F497D'>I am confused
by what appears to be a lack of parallelism in the schema, although with the
implications it has in the specification documents.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:14.0pt;color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='font-size:14.0pt;color:#1F497D'>We have been,
most reasonably, identifying the operations specific to each service. However,
I do not see these operations identified in the Schema for any service other
than Print. (perhaps I am just missing them)<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>&lt;PZ&gt;The WSDL identifies
the&nbsp; operations defined for each service (e.g. PwgPrint.wsdl).&nbsp; The
messages for the operations are defined in an associated schema (e.g.
PwgPrintOpMsg.xsd). &nbsp;The operation messages schema are really part of the
Web Service Definition but are broken out due to personal preferences.&nbsp;
The elements in the operation parameters are drawn from the PWG&#8217;s MFD
data model which are all the other schema in the directory.&lt;/PZ&gt;<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:14.0pt;color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='font-size:14.0pt;color:#1F497D'>For the Print
Service, the PrintServiceDescription includes the general ServiceDescription
elements, and then some 40+ additional elements among which are
OperationsSupported.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:14.0pt;color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='font-size:14.0pt;color:#1F497D'>However, the
other Services include just the general ServiceDescription elements and an
&#8220;any&#8221;, without any additional service-specific description
elements.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:14.0pt;color:#1F497D'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><span style='font-size:14.0pt;color:#1F497D'>Perhaps at
least the OperationsSupported element should be among the general
ServiceDescription elements? &nbsp;Although one would expect that there would
be Service-specific service description elements for each service.<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>&lt;PZ&gt;The reason
OperationsSupported was included in Print is that it is the mechanism used by
IPP to determine which mandatory and optional operations are available in the
implementation.&nbsp; It seems to me that an element listing all the supported
operations would be useful in all the services.&nbsp; It should be included in
the ServicesDescription base class.&nbsp; There may be other Printer
description elements such as the &#8220;three sisters&#8221; attributes from
IPP (i.e. PrinterUriSupported, UriAuthenticationSupported, UriSecuritySupported).&nbsp;
There are some elements that make sense to be generalized to System as opposed
to the base class for the Services.&nbsp; Examples include DeviceId,
PrinterInfo, PrinterLocation, PrinterMakeAndModel, PrinterMoreInfo,
PrinterMoreInfoManufacturer and PrinterName.&nbsp; These are useful for the MFD
as a whole.&lt;/PZ&gt;<o:p></o:p></span></p>
