I'm not a specialist in the profile architecture, so I cannot tell in
which tag this is stored; but it is definitely a part of the profile
data, and the CMM suppose to just read this out of them. The profile
creator suppose to write the illuminant XYZ values somewhere. You can
probably find this out in the ICC spec document.

Thank you so much Boris. This helps a lot.
Do you know how the illuminants are tested: where does the CMM finds
this information? The MWP tag of the Source and Destination profile?
