Yes. My guess (as I have no ISO documention) at that time was, that the number should be increased with the versions. I couldn't imagine, why the should use a number in that flag (there may be reasons for it, but I donno them).
Anyhow, I'll download veraPDF and test all variants with the actual beta. I doubt that the results will differ. If I find any other errors you can fix them at one go. Will report back (probably after lunch break). I hope nobody is in a hurry :D
I have made a test with pdf/a-2a, pdf/a-3a, they pass both the verapdf 1.8.4 and 1.9.46-dev The problem with the file $ cat unrgb.tex \nopdfcompression \setupexternalfigures[location=default] \setuptagging[state=start] \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, profile={sRGB.icc,default_gray.icc}, level=0] \setupcolors[cmyk=no, pagecolormodel=auto] \starttext \startTEXpage[offset=1em] \externalfigure[cow-brown] \stopTEXpage \stoptext is that it includes a pdf (cow-brown.pdf) and this can lead to conflicts with the specs. of the setupbackend. There is no way to solve this: even is both the pdf are pdf/a-3a ok, they can conflict. So, the safest way is always to include bitmap images. -- luigi
