It's the example of the original message of this thread, with the
modifications posted in the second message.
In the \startxmlsetups section I tried to put that condition in a
\xmlsetsetup, but I commented it out because it did not work.
Here's where I found an example with reverse-sibling:
https://www.mail-archive.com/ntg-context%40ntg.nl/msg77364.html
I was searching for "sibling" in the mailing list archive to see whether
"sibling expressions" had been implemented.
Greetings,

"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'".
In that case, why don't you show the code where you've used it
successfully and maybe we can take it from there.
