The customizing numbering seems not to work. See more detailed discussion in Q&A #1748 below.

I was excited about the [custom setting of references](https://quarto.org/docs/authoring/cross-references.html#references-1) but cannot find the correct way to set them. In the example below, I tried to change the section and figure labels to alphabetic and sub labels to roman. But as the screenshot shows, none of the section numbers, figure numbers, or their references changed in either pdf or HTML format. I tried to move `number-sections: true` and/or `crossref` under `pdf`. Nothing changed.  

What I hope to get are:

1. Customizing the section, table, and figure numbering and correctly cross-referring them. (#873 discussed this issue, but I wonder if there is an easier way to do this for HTML, pdf, and docx all)
2. Setting the numbering of some sections differently from the previous, for instance, `arabic` for main content sections and `alpha` for appendices. (#1283 post a similar demand but it seems no good solution yet)

````markdown
---
title: "test"

number-sections: true

format: 
  pdf: default
  html: default
  
crossref:
  sec-labels: alpha A
  subref-labels: roman i
---

# section 

@fig-test

# section {#sec-test1}
## subsection {#sec-test2}

@sec-test1

@sec-test2

# section 

# References {.unnumbered}

```{r fig-test}
#| fig-cap: "A plot"

plot(mtcars$mpg)
```
