ipp-not-spec-000830 fails to specify the attribute syntax for
"notify-status-code" (returned in the Subscription Attributes Groups of
responses).
It's not really obvious how to encode it, either. The operation attribute
group's "status-code" is a SIGNED-SHORT in a special location. There is no
attribute tag for a SIGNED-SHORT. "Integer" and "enum" are SIGNED-INTEGER.
I'm guessing it should be (integer(0x00000001:0x00000415))?
