Mike,

That works for me and for some internal requests.  The additional request for having Push optional would be to include a discovery attribute to locate Scanners with push capability.

What do you think about a comma separated list of push URL schemes and an empty list indicates a Pull only scanner?

Pete,

I thought we were requiring pull scan and recommending push scan because low-end devices couldn't retry a push automatically. Any push-related attributes would be conditionally required if the service supports push.  And any retry-related attributes would be conditionally required for services that do output spooling.

All,

I have conflicting notes.  I have some Push scan related attributes marked as conditionally mandatory while Pull and Push scan are listed as required.

My opinion is that Push and Pull scanning are mandated and therefore the Push related attributes are also mandatory.  For Push scanning the "http", "https", "ftp" and  "ftps URI schemes MUST be supported.

Any objections?
