Keyword values need to be lowercase to be registered... Also, is this really a Job Template attribute? How does a Client know which coordinate system to use for a given Printer?

I'm not sure how I feel about forcing the units - the resolution syntax supports both dots-per-inch and dots-per-centimeter...
(not that it matters for the registration - the Printer will tell the Client which values it will support...)

See above.

Height in pixels/lines, right?

"Source space coordinates" == "pixels/lines"?
