Are there any plans to improve the tooling so we get warnigns for this?
Otherwise I am afraid we will see a lot of patches that gets this wrong.

As a follow-up patch it would be good if example-schema.yaml
could gain some comments about the correct indentions.

Some comments in the following.

So here "- enum" do not need the extra indent.
Is it because this is not a list?

This is something I had expected the tooling to notice.
I had expected the two "- const" to be indented with 4 spaces, not two.
So there is something I do not understand.

And here "- enum" receive extra indent.

I trust you know what you are doing - but I do not get it.

Some pointers or examples for the correct indention would be great.
I cannot review this patch as long as I do not know the rules.

My request to update example-schema.yaml was one way to teach me.
(Some people will say that is difficult/impossible to teach me,
but thats another story:-) ).
