How to add raw Markdown in filter?

[Ivan Lazar Miljenovic <ivan.miljenovic-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Is there any way using a filter to be able to inject markdown into a
document using a filter and have it be parsed/processed when
converting?  Ideally, I'd like to be able to generate PDF from the
result (`pandoc --read=markdown --write=latex --output=foo.pdf
--filter=./myFilter input.md`).

Using `RawBlock "markdown"` doesn't work as the rest of the document
has already been parsed, so the contents of those blocks are then
ignored.

As such, as far as I'm aware my options are:

* Try and write my own mini-parser that handles a subset of Markdown
and thus the filter can inject the correct Haskell representation of
the intended Markdown

* Use a 2-stage process for Pandoc to first apply the filter and write
out to Markdown, then pipe the results into Pandoc to convert to PDF
(not ideal as this is for a library that should be able to just
generate whatever results you want).

Is there anything else I can try and do?
