Sorry to butt in, but is there a reason not to allow wildcards and lists?
That would allow validation and some restriction, without requiring that the
printer know every legal recipient. Something like "*@my.org,
*@my.other.org" would prevent using the printer to spam the net, while still
not restricting internal distributions or requiring a lot of administrative
work. The "any" spec would then just be "*".
As far as clients being upset at attributes they don't recognize, wasn't
there something in the IPP 1.0 RFCs that said that such things should just
be ignored?
Just ignore me if there's a major reason why this isn't possible or would be
overly problematic.
