Ahh - no. People complain enough about the size of simple matrix profiles,
converting multi-megabyte cLUT profiles to XML is simply madness.
You can of course encode binary as text and put it in an XML file (and people do),
but the result is no longer simple or understandable, and is still going to be
unreasonably large.
ICC uses a tag binary format because it's very suitable for encoding large
amounts of color information.
have the most robust and tolerant spec and reference implementation,
and test the bejeezus out the parser or else we'll end up with a new
ICC format that is interoperable with the old one only on paper.
Saying something is going to be more robust because it's in XML,
is rather like saying that a file is robustly interchangeable because
"it's in ASCII". Yes you can parse the file, but that doesn't
mean you can understand what it means.
By the way, there is still an elephant in this room, namely Windows
Color System - what is the status of that, and to what degree are
Microsoft now prepared to interact with the ICC standards process?
The elephant appears to be in a coma, since Microsoft has removed almost
all life support.
