I would need a clarification.

When using CSS, there is a fairly well working 'idiom' to build hierarchical numbering of list elements. A nice example I found is:


But I presume you guys know that:-)

Do I understand it well that what the requirement is is to be able to define that declaratively, without the necessity to build the CSS structure as above? First of all, I believe the use case should emphasize this, because the current text suggests that this is not possible with CSS (which is not true). Also... I think we will have a hard time convincing the CSS folks about the validity of that specific requirement when a mechanism already exists and is well established (I cc Bert explicitly to draw his attention:-), ie, we would need some stronger arguments.

It occurred to us that only the most rudimentary outline lists are currently supported in HTML5 with UA defaults and CSS. We can certainly use CSS to imply more specific outlining scenarios, but publishers, especially STM and legal publishers, often distinguish between regular ordered lists and highly specific outlines. For example, many hierarchical outline concatenate list item numbers based on point in hierarchy, so you could have  list with items 1.1, 1.2, 1.3, or 1.a, 1.b, 1.c. Right now, there’s no OOTB way to do this in HTML5 without building custom CSS to imply the hierarchy.
