I'd like to start contributing more. Based on the Readme, a discussion here first is recommended. The DocBook issues are perhaps my best place to start. In chronological order, that starts me at issue 1402 as far as I can tell.

I would say that is best solved by adding role="unnumbered" to the section. Section labelling (i.e. numbering) is controlled by the XSLT stylesheets in DocBook, so not numbering an individual section (rather than stop at a certain depth) would be implemented in a stylesheet customization. But marking the relevant sections would at least allow a custom stylesheet to match precisely.

If I recall correctly from the PR for this, that would just require putting ("role","unnumbered") in Header.Attr.attributes and it would come out as the role attribute in DocBook.

Protocol questions for the maintainers: 

1. Would this comment have been better on the GitHub issue?
2. Do you want issue references GitHub-style in commits to issues (e.g. "fixes #1234") from contributors, or do you prefer handling them separately?
