Hi, up to now one can use either collapsed registeres ... \placeregister[index][compress=yes] or tagged PDF ... \setupstructure[state=start] Otherwise there is an error (see below). Couldn't we also have both, or is this impossible by the logic of structure? (I have to admit, I never saw the combination of a tagged pdf with collapsed register ...) Steffen === !
