I suggest that what is being identified is the physical device, and that the
System Control Service is the proper recipient.

Subject: Re: [IPP] RFC: Identify-Printer mini-extension
Tricky. The "identify action duration" would be a new attribute (which
would require a revision of JPS3 spec - yuck).
Mike's right that IPPSIX is the wrong place to do this - the conformance
shouldn't have anything to do with IPPSIX.
I also don't think that System Control Service should get into this business
- or maybe I'm crazy and that actually is the *right* place? Should SCS,
rather than an individual service, be the target of this device-level
Someday, we need a lightweight IPP registration for whole new attributes
(in an existing attribute group), I suspect.

IMHO, these look fine. I wonder if the "identify action duration" needs to
be covered by something? Does the System Control Service need to concern
itself with this domain?
