Graeme,
Convention : Null match : Source = Destination
This is not part of the specification. You seem to be suggesting that it
should be. Valid suggestion.
As Chris Murphy suggests, if you have issues with the specification
itself, you should direct your critiques to the ICC. True, some members
of the ICC do monitor this list. But to ensure that you are heard, and
that you receive an appropriate response, you should address your
concerns in the proper forum. And to be crystal clear, this list is NOT
the right place. You will get responses, but you will not receive an
answer. Only the ICC body can respond appropriately.
Perhaps you have not yet visited the ICC web site. They have their
contact info listed right on the front (home) page. Try this link:
http://www.color.org/
The ICC welcomes feedback. However, to be most effective, I recommend
you join the organization. From time to time, the ICC does invite direct
feedback. In fact, the latest version of the spec went through public
review not long ago.
This list is a place to ask questions and (hopefully) have them
answered. Membership on the list is a privilege and not a right. We have
clearly defined what is, and what is not, appropriate use of the
listserve. I advise everyone to review these terms, and to post
accordingly.
This is the last time I will address this thread.

Note the second sentence of the spec's introduction:
"... device profiles can be used to translate color data
created on one device into another device's native color space."
The ICC specification defines a color management system for
transforming
color from one color space to another. When the source color space is
the same as the destination color space, it is generally accepted as
given that there is no need for such a transformation to occur.
I see no connection between the spec's introduction and
your assertion that it implies that there is no need to do
a transformation when the profiles happen to be the same.
Taken the way you are taking it, ICC profiles aren't meant
to translate from non-device colorspaces to other non-device
colorspaces like XYZ, Lab or PhotoCD, nor to hold spot color
information, and this is clearly not the case.
And Graeme, your emails often convey a rather coarse tone. This list is
a community. Please be nice to your neighbors.
Some people on this list have expressed appreciation of my
frank discussion of issues surrounding color, and the ICC
in particular. Sorry you're offended by me not making out
that everything is sweetness and light ..
Graeme Gill.
