Taco,

I knew that, but I wasn’t sure how to mix both. I’d say yesterday I
tried something similar to:

  \xmlsetsetup{#1}{{h3 + blockquote}../h3} {xml:section}

Which, of course, couldn’t work.

I know, I have read them many times. And I read them from time to time.
But I’m not smart enough to understand them.

BTW, is there any way to rephrase "{h3 + blockquote}" in proper Lua?

Something like "/h3/../!p/../blockquote" selected both "h3 + p" (which I
didn’t want and "h3 + blockquote" (the one intended).

Many thanks for your help,

Pablo
