Only list the properties that are present in the MIB entries - thus the non-colorant supplies don't have the colorantxxx properties.<br>
<br>
The colorantname only required for supplies with associated colorants, and the ABNF lists it as OPTIONAL (and so the IPP Everywhere tests don't require it...) but I do see it listed as REQUIRED in Table 9 (which is an error - the intent was for note 3 to apply
to all of the colorant properties...)<br>
