Have a look at
http://verapdf.org/software/
and test the file below with
$> verapdf -v -x -f 1a test.pdf
It should be ok
The icc files default_cmyk.icc default_gray.icc default_rgb.icc are
from ghostscript, put them in the same directory of the test.
\nopdfcompression
\setupinteraction
[title=TITLE,
subtitle=SUBTITLE,
author=AUTHOR,
keyword={{KEYWORD1, KEYWORD2}, KEYWORD3}]
%% For PDF/A
\setupbackend[
format={pdf/a-1a:2005}, % or pdf/a-1a:2005
profile={default_cmyk.icc,default_rgb.icc,default_gray.icc},
intent=ISO coated v2 300\letterpercent\space (ECI)]
%% Tagged PDF
%% method=auto ==> default tags by Adobe
\setupbackend[export=yes]
\setupstructure[state=start,method=auto]
\startchapter[title=Testing]
\startcolor[red]
\input knuth
\stopcolor
\input tufte
\input knuth
\placefigure[middle][fig:foo]
{This is an image}
{\externalfigure[cow.jpg]}
\input tufte
\stopchapter
\stoptext
I'm in a middle of something else now, I will look into it next days,
but you can play a bit and report problems.
