To close the loop on this, during today's IPP conference call we decided to
file an errata on 5100.9 to note that "printer-alert" and
"printer-alert-description" SHOULD NOT be reported when the prtAlertTable
is empty.
I have also included this in the latest IPP Everywhere v1.1 draft along
with a note concerning existing implementations that choose to report '' or
'code=other' for an empty table. IPP Everywhere 1.1 also now makes this
attribute RECOMMENDED for physical printers and OPTIONAL for print servers.
The IPP Everywhere self-certification tools will also be updated to a) not
require printer-alert or printer-alert-description and b) allow
printer-alert to be the empty string.

blank. Is it not supposed to be blank? I can't find in specs an explicit
statement of what the value of printer-alert should be when there are no
alerts present.
