REQ: Support :sectnums: tag for section numbering

[5ocworkshop]

Recent convert to asciidoc and just found your great project. I'm adopting asciidoc to use when writing AI prompts and I want to be able to stitch elements together from various sub-sections and I would really like the resulting master document to have auto-numbered sections using the :sectnums: declaration from the original adoc, but it doesn't seem to be supported in downdoc today, is that correct or am I perhaps missing a switch or detail?
