How to access reference information in a template?

[fredguth]

Description

Still on the saga to build a Scielo xml format template (#12251, #12300) that is validated by its xml checker[^1][ˆ2]

I used jats publishing format template as an example to create my scielo.template.

The problem is that I don't know how to access what is inside $back$.

I just use it like

...
<back>
$if(back)$
$back$
$endif$
</back>
...

and it renders references and footnotes.

The references in ref-list are being generated like

 <ref id="ref-sinhoretto2014a">
        <element-citation publication-type="article-journal">
          <person-group person-group-type="author">
            ...
        </element-citation>
      </ref>

while Scielo format mandates the use of the <mixed-citation> tag as in :

<ref id="B38">
	<mixed-citation>CENTRO DE PESQUISA E DESENVOLVIMENTO EM TELECOMUNICAÇÕES (CPQD). Modelo de referência - Sistema Brasileiro de Televisão Digital Terrestre, 2006. Disponível em: &lt;<ext-link ext-link-type="uri" xlink:href="http://sbtvd.cpqd.org.br">http://sbtvd.cpqd.org.br</ext-link>&gt;. Acesso em: 05 Mar. 2009.</mixed-citation>
		<element-citation publication-type="book">
			<person-group person-group-type="author">
			...
		</element-citation>
</ref>

The text inside the <mixed-citation> tag is the format the reference is rendered in a html or typst format.

[ˆ1]: I have built a mwe repo with the most minimal example I could think. It will also be used to another problem I found while trying to create this custom format (#12300).
[ˆ2]: I know it is not ideal the proliferation of questions, but my first question (#12251) was a little bit confusing and nobody commented. Also, I thought that each of the 2 problems to which I reduced my problem (this question and #12300) might be useful for someone searching later. I don't know.

Just noticed that running pandoc directly renders <mixed-citation> in the output:

❯ pandoc index.qmd \
  --standalone \
  -f markdown \
  -t jats  \
  --template=scielo.template \
  --citeproc \
  --bibliography=refs.bib \
   --csl=abnt.csl -o output.xml

output.xml

...
<back>
<ref-list>
  <title></title>

    seleção do suspeito. <bold>Revista Brasileira de Segurança

but does not render the <element-citation> tag
