BTW, is there any way to rephrase "{h3 + blockquote}" in proper Lua?
I was wondering about that as well, and I really had no clue how to do that.
Some
reading and studying later, I realised that there is a preceding-sibling:: axis.
That is not documented in xml-mkiv.pdf I think, but it inherited from xpath,
and that means this works:
\xmlsetsetup{#1}{blockquote/preceding-sibling::h3[-1]/} {xml:section}
“Take all blockquotes, then tests their immediate preceding siblings (index [-1])
that are h3."
But the CSS version is nicer. Still, both solutions fail on generic input.
Sorry, out of clues
\startbuffer[demo]
<xml>
<div class="section level3">
<h3>One</h3>
<p>Standard paragraph</p>
<blockquote>
<p>Quoted text</p>
</blockquote>
</div>
<div class="section level3">
<h3>Two</h3>
<blockquote>
<p>Direct quote</p>

</div>
