Yes, the three CUPS qualifiers like GCM. And Oyranos' CUPS module supports 
arbitrary qualifiers/keys coming either from a PPD or a profile.

The keys for the meta tag are not generally specified for printers. They 
are to be specified by the actual used PPD or have at least to match keys 
used in a given PPD. The mechanism to mark PPD keys as colour related 
is described on the OpenICC wiki:

Perhaps a prefix like PPD_, CUPS_ or something more general like 
COLORPRINT_ could be specified. Ideas are welcome. And a specification 
needs some initial outlining of a basic idea how matching shall occure. 
Then it becomes clearer for profilers what to write in the meta 
tag and what not.
