I'm sorry, your question makes no sense to me. We follow all of the KDE Userbase guidelines to the letter. Typesetting labels? I have no clue to what you refer. Can you cite an example?
Use bold text to highlight
- Common labels that are not user-configurable
Aside: I am afraid the process of converting wikitext to DocBook will have to kill all existing formatting, or the resulting DocBook will be substandard.
Are you sure? ;)
