Great job Roger!
I have comments on several of your replies to Jay.

Is Jay's suggest eliminating some type of file referencing that is not
a URL? I believe that we do NOT want an IPP server to access print data
via a simple file reference (which is not a URL). This concept is
already in PSIS (XDPA) and it turns out to be a bad idea because the
client can easily pass in a path name that is either inaccessible to a
server or references a different file from what the client intended. I
like the URL file reference because it is unambiguous.

However, it is the case that BSD protocol does return "printer status"
along with a list of jobs and their attributes. Printer status is
useful in this situation even though it may not fit into the model
in a clean way.

Some people have commented that they like the default being first. I am
not so sure. I can see the case where the order of potential values should
be the same for each printer, but the default is different for each.
HTML solves this problem by having a special tag to mark the default value.
