How to use CSL to style classical texts in bibliography using "@classic"?

In philosophy in general, Plato’s texts are mostly cited in a short format, e.g. “Plato, Politeia 327a–329a.” I tried to create a CSL style for this BibTeX entry:

@classic{Politeia,
    author={Platon},
    title={Der Staat. Politeia.},
    shorttitle={Politeia},
    translator={Rudolf Rufener},
    year={2000},
    publisher={Artmeis \& Winkler},
    location={Düsseldorf, Zürich}
}

But I cannot style it. Using

<choose>
  <if type="classic">
    ...
  </if>
  <else>
    ...
  </else>    
</choose>

does nothing, unfortunately. The entry always uses the else-branch, although the BibTeX file says classic.

Is this intended and am I doing something wrong or is that a bug?

Hello. Typst supports BibLaTeX format, not BibTeX. Neither of them list the “classic” entry type. Since non-standard types in BibLaTeX fall under standard “misc” type, I would assume all custom ones will go under that too. Which I didn’t find in citationberg/src/taxonomy.rs at 67db988c7155f17b2e0aff9aabcd9a00745e4c04 · typst/citationberg · GitHub, but I did find “classic”. I also found both in Hayagriva code for CSL, but there is this:

So I guess it’s not implemented.

I feared that, but thank you. Although it would be very nice to have it or at least another possibility to format classic texts because without this possibility it is very hard to write documents with Typst that target a philosophical audience.
