@mprpic Could you please double-check?

@wurstbrot Thank you for your contribution. Due to the rules of OASIS, we might not be able to accept your suggestion via a Pull Request (even though we known it is often easier to create a PR than trying to describe where a file is). Knowing that you can't use the formal way via csaf-comment mailing list right now, we will discuss the issue.

I'll set the PR to draft for now. Due to the formal rules, a TC member might need to create the PR. Nevertheless, again: Thank you for your contribution.

@sthagen, @santosomar, @mprpic: I would suggest to add a disclaimer to the file instead: See #704
