I wonder why the ambitious CommonMark project did not look into adopting any of these. Regarding references, this is great, but I was referring to internal within the document ones, not external. For example, in "Article I" you mention "Article II, Section 3", which should change to "Article III, Section 3" if I insert a new article between the first and the second or to "Article II, Section 4" if I insert a section.
