Stil ConTeXt is the only TeX-based typesetting system that can produce tagged PDF - this is a unique feature, thank you Hans!

I have, however, found that the following MWE produces wrongly nested tagging information. Specifically:

- The itemization with columns (\startitemize[columns]) is not contained in an "itemgroup"

- The second itemization (without columns) is tagged outside of the "sectioncontent"

(Maybe the second issue is a consequence of the first.)

I am afraid but this might be a bug. Thank you for any feedback.

Cheers,

Christoph
