Dear list, I have the following sample: \setuphead[chapter] [beforesection=\TeX, aftersection=\TeX] \starttext \startchapter[title=Chapter, beforesection=\ConTeXt, aftersection=\ConTeXt] This is my chapter. \stopchapter \stoptext After checking i-context, the options for the second pair of brackets are: KEY = VALUE Well, I think this is the standard case. Aren’t values inherited from \setuphead? What would be the valid keys for this case? I need to use \xmldoif in beforesection and aftersection. As far as I can see, it doesn’t work inside \setuphead. What would be my approach to deal with "\xmldoif{#1}{.[@id='topic' and contains(@class,'hidden')]}" in beforesection? I realize that "\definehead[specialchapter][chapter]" would be a workaround, but I would like to find a more proper solution. Many thanks for your help, Pablo -- http://www.ousia.tk
