Put politely, BS. A single light spectrum can be reduced to an XYZ in precisely
two ways, for either a 2 degree or a 10 degree observer. The latter is rarely
used, which leaves one way.
XYZ is a reproducible and measureable colour description which has been an
international standard for the last 63 years.

Ah. OK, that is not what *I* was trying to say. I just threw up a rag bag of
technology that might bear upon the problem and, as it happens, TIFF does do
quite a lot of good things. Clarification, the TIFF spec does ;-)
But I did not mean to present TIFF as a universal panacea.

Qoute from the Tagged Image File Format spec again, just as an example you
understand ;-)
"A tag based scheme cannot guarantee painless growth. But it does provide a
useful tool to assist in the process"...
" TIFF will be enhanced on a continuing basis as new imaging needs arise. A high
priority has been given to structuring the data in such a way as to minimise the
pain of future additions"
