Feature request: Differentiated numbering styles for nested lists

[wheresrhys]

To me the content below is, though semantically correct from a markup standpoint, quite confusing to digest because of just having a single numbering system

Would it be possible/desirable for o-layout to apply different numbering styles to each level. ie.e. top level 1. 2. 3., second level a), b), c), third level i, ii, iii ? I see that lower-roman and lower-alpha are available in CSS, but not sure how nicely they'd play with the more complex mechanism used by origami to output the indices
