However the Devices Profile for Web Services specification contains a chain of definitions that does seem to limit the applicability. I tried to find the mail thread from long ago that I had when I was looking into using WSD to also make the IPP endpoint visible. I could not locate the mail notes. As I have stated I have no objection to making IPP discoverable using WSD. Since many vendors currently use WSD we just need to insure that it is acceptable to apply the technology to non-SOAP based services.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Pete<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>PS If you have no objections, I’ll post this response to the IPP mail list.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D;background:yellow;mso-highlight:yellow'>HOSTED SERVICE</span><span style='color:#1F497D'> <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>A distinguished type of SERVICE that is hosted by another <span style='background:yellow;mso-highlight:yellow'>SERVICE</span>.
