I am writing my own pandoc to latex converter using panflute and would like to attach attributes to Math elements. I have tried the following syntax, but it seems that the attribute is not being picked up by panflute:

```

$$x=y$${ a=b }

```

I did some of my own research to figure out what I was doing wrong. And a couple of things became apparent:

- On the one hand, it looks like pandoc might not support this:

    - https://github.com/jgm/pandoc/issues/684

    - https://github.com/jgm/pandoc/issues/5286

- On the other hand, `pandoc-crossref` seems to be able to handle this syntax:

    - https://github.com/lierdakil/pandoc-crossref

    - https://lierdakil.github.io/pandoc-crossref/#equation-labels

Is this currently supported by pandoc? If not then how is `pandoc-crossref` able to handle it? Thanks for your consideration.

Regards,

Amine
