Re: How to resolve citations inside attributes

[John MacFarlane <jgm-TVLZxgkOlNX2fBVCVOL8/A@public.gmane.org>]

Citations are only recognized when they're parsed as markdown.
@key in a code block or attribute won't be parsed.

You could use the pandoc Lua 'read' function to parse the
contents of your attribute as Markdown and then do something with that.
