+Subject: [PATCH] For ICC profile validation, have cups id iteself as DeviceN
+
+Give the range of color spaces and models that cups supports, we can't
+reasonably provide (or expect others to provide) output ICC profiles for all
+cases.
+
+For the purpose of profile validation, have it claim to be DeviceN and benefit
+from the extra tolerance in profiles allowed for that class of device.
