Hello,

PWG 5100.9 allows an alert code(PrtAlertCodeTC) 'configurationChange' for printer-alert. This value sounds like it is defined to be an event rather than a state. 

If you think that it is a 'state' rather than an 'event', can you please explain how? If it should be treated as a 'state', then should devices initiate a self-determined-timeout value to come out of that 'state' (this sounds like a method to morph an event into a state)?

If it is indeed an 'event', then please explain why this attribute (printer-alert) is part of the REQUIRED table in IPP FaxOut and IPP Scan specifications when the IPP operations for event subscription themselves are optional.

Thanks and Regards,
Somasundaram.
