Section 19 (Appendix F) presents sample PrintJobTicket content, and Section
20 (Appendix G) presents sample PrintJobCapabilities content. But there is
no example PrintJobReceipt. Add a new appendix section (or perhaps
sub-section) presenting the example content for PrintJobReceipt so that a)
its existence is obvious; and b) that the connection between the 3 can be
Priority changed to 'Moderate'.
