@thbar I need instruction how to fix parent branch stuff.

@Micovec I wonder if we could add a URI validation rule for XmlnsUrl.

@skinkie, there is one commit to backport from v2.0 to v2.1-wip. I have embedded it in Matthias' latest PR (#1060). When we merge that one, then all upcoming PRs on v2.1-wip should pass the 1st CI check.

@TuThoThai how is this 'check parent branch' solvable?

@TuThoThai how is this 'check parent branch' solvable?

2 ways of doing it, generally speaking:

• create a PR that also targets v2.1-wip every time there is a change done on v2.0, so both are always aligned
• embedd in the latest PR for v2.1-wip the commits that are present in v2.0 and not yet backported

I went with the 2nd option in the PR preceding this one (#1060). I am waiting for review on that one to merge. Then, I will run the CI again on this one.

I think both ways are not aligned with how git is supposed to be used. I think it is the maintainers jobto regularly synchronise these branches and not to be done on the individual PR.
