Hi all,

I would like to open the PDF/A topic once more.

First, I would like to thank Alan, Luigi, Pablo and Henri for their pieces
of help and information.

========
Summary:
========

(a) where I can find the set of original default*.icc files,

# Alan: /usr/local/share/color/icc/ghostscript

This must be dependent on the version of operating system or on something
else because on computers I have permission to work on no this subtree is 
present.

# Luigi: tex/texmf-context/colors/icc

In standalone versions I tried during March and April and Pablo in June, there 
is really this special directory
but we found there only one of the files -- default_gray.icc. Other 
default*.icc files
(default_cmyk.icc, default_rgb.icc) which are mentioned at 
http://wiki.contextgarden.net/PDF/A
were not present. Similarly at http://www.eci.org/en/downloads.

# Henri:  http://dl.contextgarden.net/misc/iccprofiles/complete_ICC_profiles.zip

Good deal -- here one can really find all three default*.icc files mentioned at
http://wiki.contextgarden.net/PDF/A, but with no visible link to the
mentioned zipfile from this page.

========

(b) what is the reason why these files are not included in the TeXlive and 
garden installations,
(c) if it is possible to add it there for future, and

# Luigi: They are not included in texlive for some copyright issues.

What is the difference between texlive copyright approach and context 
standalone copyright approach?

I read a few documents about licences for icc files and it seemed to me that 
the redistribution is possible,
for non-commercial use without restrictions, the redistributor is obliged only 
to add the corresponding 
licence document to the software containing the icc file(s) and must not change 
the name of the file(s).

So, is possible to add the missing two default*.icc files to the context 
standalone version?

========

(d) if the produced PDF (with \setupbackend[format={pdf/a-1b:2005}...]) is
PDF/a compliant when these icc files are not present and the whole content
of the document is only in black (i.e. no grayscale, no colours).

# No reaction. :-)

This question is important only if the default*.icc files are not (will not be) 
present and used when the PDF file is generated.
Has somebody got any idea whether the PDF/A without icc files is accepted as 
PDF/A or not?

========

The best,

Tomáš
