FloatRefTarget does not include all crossrefs

[xtimbeau]

Bug description

The point is to build a listing of crossrefs by type over a website generated by quarto.

I managed to use @tobydriscoll crossref-listing extension, and I tried to look into the new FloatRefTarget. From what I understand, this is not collectiong all crossrefs. Consider the example there:

_quarto.yml

project: 
  type: website
  
format: html

filters:
  - peek.lua

index.qmd

---
title: a test
---

::: {#fig-afigure}
some content
:::

::: {#tbl-atable}
some content
:::

::: {#tip-atip .callout-tip}
## some title

some content
:::

peek.lua

function peek(f)
  quarto.log.debug("------- FloatRefTarget ")
  quarto.log.debug(f.type)
  quarto.log.debug(pandoc.utils.stringify(f.caption_long.content))
  quarto.log.debug(f.identifier)
  quarto.log.debug(f.parent_id)
end

return {
  { FloatRefTarget = peek }
}

When quarto render --trace is run from the console one gets what's below, that is to say all div except #tip which is a crossref looking a lot like the others ? (the same can be obtained with the chunk labelling stuff).

(D) ------- FloatRefTarget
(D) Figure
(D)
(D) fig-afigure
(D)
(D) ------- FloatRefTarget
(D) Table
(D)
(D) tbl-atable
(D)

That's correct, but isn't a bug: not all ref targets float. Equations, for example, are also cross-referenceable and not targetable by FloatRefTarget.

You'll need to target Callout to find those nodes.

(In the future, please consider asking a Q&A question first. Thanks!)

OK, that's clarifying. However, if I wanted to produce the same fields as for FloatRefTarget, is there a piece of lua I can get inspiration from ?
