If the attribute specifies the profile (tiff-profiles-supported) isn't
this a better resolution than 'faxbw' and 'faxcolor'? Are you proposing
an attribute such as "tiff-applications-supported" which would only
include 'faxbw' and 'faxcolor'? The BW vs Color can be determined from
the "color-supported" Printer Description attribute and the profiles give
even better information.
