Hi, I am closing my dissertation (finally) but I had to realize that subnumbering of formulas is still not working in mkiv. Unluckily going back to mkii is not an option for other reasons. For that I really need help to bring back a fully working formula numbering. I searched the entire wiki and mailing list for possible examples and put all in one test file - I got non to work but maybe I also made a mistake somewhere. Additionally I wrote everything on my talk page of the wiki: http://wiki.contextgarden.net/User_talk:Zenlima If every method has to be fixed my priority is the \NR[+][c]-method. Maybe someone can give additionally hints how to get a proper list of formulas. I attached the test file with its pdf result in addition to the wiki page. Thanks H.
