Thank you for your answer, Thomas. I tried something similar (putting a \noindentation at the end of the "incipit" paragraph, but it failed if I put a \blank after that).
The sibling part In the book of the history of luatex (v 0.50) it is said that the sibling functions would not be implemented soon, but at least 3 methods have been implemented. From the release notes 8/5/2010 (http://wiki.con textgarden.net/Context_2010.05.08): "implement following-sibling(), preceding-sibling() and reverse- sibling() lpath methods" If you search for "sibling" in the mailing list archive, you find a pair of threads. I've found no other documentation. "reverse-sibling" is ConTeXt specific and very useful: it's a "reversed preceding-sibling", so that you find the nearest sibling at index [1]. I've used it successfully in a \doif statement, but I failed in translating it in a \xmlsetsetup statement, to tell ConTeXt: "this setup is for an element p whose nearest preceding sibling p has class 'incipit'".
