That will teach me to write an email when I'm walking out the door on Friday.
You're right Mike that I was talking about job-uuid and not job-uri. I'm just making sure we're not adding another job specifier to the uri/id mess we have now.

Hi Mike and Mark,
True, RFC 2911 allows "job-uri" alone to be specified
for *some* Job operations.
But RFC 2911/2910 do not specify the relationship
between "job-uri" and "printer-uri" (which is a bug).
So the later RFC 3510 ('ipp' URI Scheme) was unable
to specify any such relationship.
Which is why I've seen quite a few IPP implementations
that do NOT accept a "job-uri" value as HTTP request-URI
(i.e., as a protocol endpoint) - since it's implementation
dependent anyway, they simply refuse to honor stand-alone
"job-uri". I have always advised my clients to avoid the
assumption that "job-uri" is a safe protocol endpoint.
IPP Everywhere cannot really fix this ambiguity. And
just saying that "job-uri" should work won't help any.
OTOH - "printer-uri" plus "job-id" is safe and reliable.
My two cents.

media-size-name it is, then...

Actually, only job-id needs the printer-uri. job-uri can stand alone, per 2911...
