Hi, ConTeXt mkiv is the only TeX-based typesetting system that can produce tagged PDFs and this is a really useful feature. Unfortunately, footnotes seem to upset tagging. MWE: \setuptagging[state=start] \starttext Text\footnote{Note} \stoptext In the resulting PDF, the structure tree seems okay to me, but the content stream is defect: 0 g 0 G BT /F1 11.955168 Tf 1 0 0 1 280.5345 760.6422 Tm [<00520067>]TJ ET /document <>BDC BT /F1 11.955168 Tf 1 0 0 1 70.867 702.3845 Tm [<0068>82<003200740069>]TJ ET EMC BT /F6 7.970112 Tf 1 0 0 1 94.2752 706.0772 Tm [<0052>]TJ ET EMC q 1 0 0 1 70.867 131.9542 cm []0 d 0 J 0.3985 w 0 0 m 85.0373 0 l S Q /descriptiontag <>BDC 0 g 0 G EMC BT /F6 7.970112 Tf 1 0 0 1 61.6535 122.7515 Tm [<0052>]TJ ET EMC /descriptioncontent <>BDC BT /F5 9.96264 Tf 1 0 0 1 70.867 119.0587 Tm [<004C005100690032>]TJ ET EMC Clearly, in the content (around line 10) we miss something like /sup <>BDC I hope that this is a minor issue in the processing of footnotes. I would very much appreciate if you could fix this bug. Cheers, Christoph
