Can a empty profile be published by a printer for listing the colour 
related options?
printer-icc-profiles={ print-color-mode='' printer-resolution='' }

That way clients know the required meta data for profile association.
E.g. Gutenprint will come assumedly with no profiles for most of it's 
supported printers.
