Smith,

Aside from maybe EPX, I'm not sure these really fit.  And given that they are pulled directly from 5110.1 (which defines the semantics, etc.) and widely implemented (probably in 800M+ printers) I don't think there is a lot of value in holding them for a spec.

These are based on the corresponding PWG Hardcopy Device Health Assessment Attributes [PWG5110.1] and require that each of these attributes have the same cardinality (number of values), for example:
