That's a good solution, in general. Note that you can omit the
PANDOC_READER_OPTiONS and PANDOC_WRITER_OPTIONS, in which case the
default options will be used.

Even simpler would be to replace the full snippet above with

```lua
pandoc.Plain(
  pandoc.utils.blocks_to_inlines(
    pandoc.read(el.attributes.caption, 'markdown').blocks
  )
)
```

This should give you the result you need and has the advantage of
working with any output format.

Does this solve the problem? If not, could you add a little example for
us to look at?

Cheers,
Albert
