[NTG-context] Interrupt section numbering

Hi together, this should be straightforward, but I can’t find how to do it: I need to interrupt the automatical section numbering, because I need an order like 1 1.1 1.2 2 2.1 2.2 3a 3a.1 3a.2 3b 3b.1 4 4.1 etc. In enumerations I can use start and continue - but in sections? I could cope with numerical-only tweaking in this case (I’d set a/b in the title). Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net GPG Key ID 1C9B22FD
