Ira,

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

Hi Smith,

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
operation?

Someday, we need a lightweight IPP registration for whole new attributes

(in an existing attribute group), I suspect.

 

Cheers,

- Ira

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?

an action other than 'cancel', which by definition stops any active
