A trick I have been using is to include custom bits as code/raw
spans/blocks with classes/'formats' and parse and convert them to an AST
fragment in a filter, which is way easier than writing a custom parser for
whole files (and used to be the only viable option.) TBH I have mostly done
so in JSON filters written in Perl, but now that lpeg and re are available
in Lua filters they are a serious contender too.

A tip: if custom bits in syntax X are much more common than actual code
elements it makes sense to leave the former unmarked and give the latter a
pseudo-class `.code` if you don't want them highlighted.
