case in Georgian list numbering

I've only been able to find two implemenations of CSS2's
'list-style-type: georgian'.  Mozilla uses capital Georgian letters.
Opera uses small Georgian letters.  (css3-lists specifies the latter.)
My testcase is:  http://dbaron.org/css/test/2005/georgian-lists

Does anybody know if Georgian list numbering is typically uppercase or
lowercase?  Can it be done either way, or is only one of them
acceptable?
