The thing is that there were *lots* of Kernel documents that were already following ReST syntax, some requiring minor adjustments. Yet, each one used its own way to indent the several levels. On most of those, the indentation was: First ===== Second ------ Having to rewrite all tags at the entire document with no real gain, while having a batch of thousands of documents left to be converted from .txt to .rst was simply a waste of resources. At the documents I converted myself, I just kept whatever level indentation it was already there. Going further, even now I would really prefer not needing to review patches that are just changing the tags for each indentation level. Again, this would be a waste of resources. I would very much like to receive more patches adding kernel-doc documentation and ReST changes to document the Kernel core APIs. Now, for *new* documents, I agree that it makes sense to use a standard way, at least up to level 3, like: ===== First ===== Second ====== Third ----- Which is quite intuitive to me. > > > >> Improving the documentation on documentation is great, but I think it's > >> a bad sign when length of the notes and warnings on something far exceed > >> the length of the thing being documented.

At least at the charset I use here, `~` is bigger than `-`. For me, it sounds counter-intuitive to use it there... Personally, i prefer `^` for the 4th level. Yet, the forth level (and the following ones) generally happen when someone needs to add something to an already-existing document. I doubt anyone that already works with ReST would ever look at the doc-guide if they need to add a 4th/5th/... level on an already existing documents. So, IMO, it is pointless to define or expect that all docs would use the same level markup after the third level. > > For instance:: > > > > ===== > > First > > ===== > > > > Second > > ====== > > > > Third > > ----- > > > > Fourth > > ~~~~~~ > > """ > > I'm more inclined to keep "level"s in the example. Agreed. Regards, Mauro
